Dear all,
as the topic says, for a td style game which kind of graphics would you prefer, what would you do? Easiest to do for me would be plain 2d top down but isometric (2d) or real 3d (isometric) as well would be an option, too.
That might sound like a stupid question but I really scratch my head about that one. 2d has its benefits as well as 3d…
Oh well I might add, this is for mobile platforms!
I honestly don’t think it matters nearly as much as the other aspects of the game design. You could draw your towers as little squares, and the attacking units as little circles with stats on them, and it’ll still be a fun game to play if the design is good. Conversely, your TD game could be an immersive virtual-reality experience with surround sound in a motion simulator, and if the gameplay is no good, it would still suck.
FWIW, my favorite TD game is Bloons TD (any version). All other TD games I’ve played have felt pretty lame in comparison, even though some of them have much fancier graphics.
So, develop your game using whatever sort of graphics are easiest/quickest for you, and then focus on the gameplay until it’s truly fun to play. If you can’t find the fun, you haven’t wasted your time doing a bunch of fancy graphics. And if it is fun, you’ll be in a much better position then to decide what sort of presentation works best for your game.
What’s to add? @JoeStrout said it perfectly. And, moving this to the general forum.

Thanks for your comment Joe! To go a bit more into detail it won’t be a classic tower defense game but has td elements and will include multiplayer so people can play against other bases. 
I think I will go the 2d route which I know better.
