System comparison GURPS Dungeon Fantasy vs DnD 5e...?

[DocRailgun]

It depends on what kind of game you'really looking for. Yes, DF is supposed to be a munchkiny sort of game, but you can also easily do a low-powered gritty game (as in classic AD&D, where a party fought one encounter with some fire beetles and then had to hobble back to town to rest). Those sorts of games aren't possible anymore in 5th edition without a lot of work on the GM's part - most everyone has more hp now (wizards even have a d6), ample chances to heal themselves with hour long rests, arcane spellcasters in armor (though with high Dex, light armor is as good as heavy armor), and almost anyone can have a blaster spell they can cast each round if they want to be a High elf, take a level in a spellcasters class or spend a feat at 4th level.

On the other hand, 5th ed. doesn't have the unstoppable juggernauts of mid-to-high level 3.5 because there aren't a million ways to get bonuses - there no more of the stackable armor class bonuses l, for instance. The stat-boosting spells of 3.5 (Bull's Strength, etc.) don't actually increase stats in 5th ed., they just give advantage on that stat's tests, so adventurers won't be getting +10 Str and Dex (+something arcane, +something divine, +something profane, etc.) before battles.

The nice thing is that there are reasons to play fighters now, especially if you want to play a gish. There's niche protection if you want it or you can end up with PCs who can do their class' job, cast one of those blaster can trips, and cast some minor healing by 8th level even without sacrificing any main class levels.
