Read the section on multi-class characters again. Once a skill is a class skill, it is always a class skill.
Human Rog1/Sor3 vs. Brd4 With a 14 Int.
(44 + 15) 69 sp vs. 49 sp
Rog1 is 8+int (10) * 4 (+4 for human)= 44
Sor3 is 2+2(int)+1 (human) * 3 = 15
Brd4 is 6+2(int) * 4 (+4 for human) = 28 + 7 more sp * 3 more levels = 21 more. 28+21 = 49
20 more skill points.
I didn't really want this to be a Bard debate, but I think the Bard is horrible as designed, so it's kind of personal with me. 
Let's continue, shall we?
Bards have Sorcerer-based casting, which means that can never pick up new spells like the 2nd ed. Bard could. They're less flexible than wizards, which doesn't make sense to me.
And Bardic music sucks. Give me one example of where you would use Countersong that doesn't include a Harpy. Inspire Courage is the only useful song there is.
And Bardic Knowledge is just as weak. But, if you want those two abilities, just take 1 level of Bard.
I use Fascinate, Suggestion, Inspire Competence and Inspire Greatness frequently. Inspire Courage I use in maybe 95% of combats. Countersong I agree is not so useful, but it does also work on gibbering mouthers, yeth hounds, androsphinxes (or androsphinges), red slaadi, shadow mastiffs, howlers, dragonnes, satyr pipes, krenshar shrieks, perhaps destrachans, vrocks, trumpet archons, allips, the spells sound burst, command, suggestion, shatter, shout, greater command, geas/quest, wail of the banshee, enthrall, mass suggestion, and of course other bards' fascinate/suggestion abilities and some virtuoso songs. That's er... a few more than "one example," so you have been rebutted by your own standard.
And bardic knowledge... let's see with a +20 you automatically know legends about powerful magic items and more than 1/2 the time get petty magic items. With a +1... well, occasionally you might know something about a very famous powerful item. Do the spells Legend Lore and Identify ring a bell? Does it occur to you that this ability is like a powerful divination spell with no casting time and no limit per day? But I guess in your campaigns, information doesn't matter. Like in your games, you just kind of go and kill monsters, you don't ever have to like figure anything out?
Your "take a level of bard" answer also is also empty. Bardic knowledge and bardic music are both level dependent, BK is +1/level and BM is 1/day/level. The difference between 1 level of bard and 4 (or 10 or 20) is pretty substantial. Inspire Greatness also has bard level-based number of targets/use. At 18th level a bard can cover 4 at a time with Insp Greatness, and he can do it 18 times a day.
You keep saying "Once a skill is a class skill, it is always a class skill," but do you know what it means? The fact is that if you front-load the rogue level the way you did in your original post, your rogue skill points are limited by being 1st level. Perhaps you are also unaware that the "always a class skill" rule only applies to the skill maximum, not the skill cost (PHB p. 56)? Your bard 1/sorc 19 can only spend his sorc skill points as class skills for sorc class skills, not for bard class skills, i.e. most of his bard skills will be basically worthless at that level. Sure, you can buy perform as a sorc, but at 2 pts./level, it gets expensive fast.
I agree, this is obviously just something personal with you.
...
So, let's compare, shall we? The Brd/Sor has fewer skill points, but still a fair number. Has 19 less hit points, but at 20th level, the difference between 51 hit points and 70 hit points is negligible.
Spells - whoa. The Bard's spellcasting abilitiy is paltry compared to the brd/sor. It doesn't even begin to compare. The brd/sor has 4 more cantrips, 2 more 1st through 4th level spells, 2 more 5th and 6th, and then on top of that has 6 7th, 6 8th, and 4 9th level spells. That's some serious firepower.
Plus, the Brd/Sor has just as good ability with Bardic music since he could continue to put a point into Perform at every level, and have 23 ranks in Perform at 20th character level. He's JUST as effective with Bardic Music as the straight Bard.
The ONE and ONLY ONE reason to play a Bard past 1st level is to increase the Bardic Knowledge roll. But, the Brd/Sor gets a roll he just adds only a +1 to his die. The Bard adds +20. So, the straight Bard ends up knowing a few more scattered bits of knowledge. Whoop-de-freaking-do.
I'm sorry, my friend. The case against the bard IS as cut and dry as I make it out to be.
The phrase is "cut and dried", BTW, not "cut and dry."
Again, you keep ignoring the idea of balance. Does a 19th level sorcerer have more spells than a 20th level bard? Of course! The bard also has a 50%+ higher BAB and almost twice the Ref save, not to mention 37% more hit points. Though since you snort at a mere 1/3+ of you hit point total, you must think then that a bard is about as good as a cleric in melee, since they have the same BAB and a bard only has 21 less hit points as 20th level (only a 22% difference).
