My experience with playing Rogues is that while they're clearly better off than Fighters and Barbarians they're also clearly better off if they are Arcane Tricksters. Having access to spells like Invisibilty, Disguise Self, Misty Step, Fog Cloud etc just give you a lot more range of options to use your skills and expertise. (Eg if you can turn invisibile you can use your expertise in Stealth in circumstances where it wouldn't otherwise be viable.)
All of which are available a limited number of times per day and ultimately don't add that much to what you can do already (misty step allows for bonus action movement which you can already do, invisibility allows you to hide which you can so in most cases anyway, disguise self is easily replicated with a disguise kit etc).
Youre not really adding new utility with those listed spells. Just slightly improving things you can probably already do, and only a limited number of times per day.
Compare a handful of spells per long rest to the Masterminds tossing out advantage, the Scouts extra skills and at will reaction movement and so forth.
Remember, we're assuming a 6 encounter 2 short rest adventuring day median here, spanning several hours with encounters lasting an average of 3-6 rounds each
