This may sound stupid, but how about a 15th level 1e fighter vs. 15th level 3.5 fighter? (I get the feeling THAC0 may be a problem.)
1e fighter wins. All he has to do is strip himself naked, getting an AC of 10. With his THAC0 he would easily hit the high AC 3.5 fighter every round, while the later would have a harder time breaking through the 1e fighter's 10 AC. =D I mean, really, even a level 1 1e fighter with a THAC0 20 can hit a 15th level 3.5e fighter with a 20+ AC. =D
Seriously, though, I dont think even a rough estimate can be given, unless some serious math is put on the works. A damage dealt by characters in both versions is not a constant number. it is a variable, and thus can not be easily compared. It is a variable, because it is interlocked with the rest of the system it is part of. While some numbers may remain the same in both editions (like the natural AC being 10), they are also variables of the 'balanced' equation of that system. In 1e, the lower the AC the better. In 3e+ the opposite is true. And yet in both editions characters have a beginning natural armor of 10. That 10 is not a constant. It is a variable. You cant just say that if a 1e 15th level fighter deals X damage and a 3.5e 15th level fighter deals 1.5X damage, that a 3.5e fighter is 50% stronger/more dealy than a 1e fighter. Because that increase in damage is probably counterbalanced somewhere with another variable. In 2e, for example, a 13+ level fighter with a melee weapon specialisation could attack 5 times in 2 rounds without any penalties to his attack rolls. That's another variable on the equation of the 2nd ed system. So it is really hard to tell, because you cant treat those numbers as constants. They are variables. Ghouls in 2nd ed have 2 HD while in 3.5e they have 3 HD. Tarrasque in 2nd ed has 300hp while in 3e it has 840hp! A great wyrm GolD Dragon in 2nd ed has 24 HD(HD being a D8 for all monsters in 2nd ed) while a Great Wyrm GOld Dragon in 3e has 41d12+451 hp!! If monsters are also tougher, then that counterbalances with characters making more damage. And that doesnt mean that monsters are also tougher in 3e, because those numbers are variables as well. For the system to be balanced, the monsters need an increase in their statistics because of a increse in the statistics of the characters.
And that's the feeling I get from 3e+. Before 3e+ some people would get confused with the fact that, for some things, the higher the number the better, while for others, the opposite was true. To try to simplify things, in 3e they changed that. The higher the better. To anything. So you have a new system equation which is adding numbers up all the time. You can even see a reflect to that in the 3e MM. In 2E you would get the CLimate, Diet, Intelligence, Activity Cyclke, etc information first, and numbers later. In 3e+ you get the numbers first.
Only my two cents, though.
