I think it's a matter of preference only. Though I am a long PS2 and PS3 controller user, I can firmly grip the 360 controller. Playing Gears of War was a charm with it. I played long sessions of Fifa too. But it seems the long time play put some stress on the hand specially the left one.

PS3 controllers pressure sensitive buttons are very good, 360's Trigger button is also better. I would love if I could use a PS3 controller on the 360 or vice versa.

I already knew this :)

Oh I see now. It's still undesirable. Going from a controller to a wheel is a huge difference for me mainly because of the control I get over the brake and throttle levels. But even with a controller I try my best to not be applying full pressure. It does affect the car.

1.  I don't think anybody ignores the 360 D-Pad, it's awful.  The clicky-twist one is better, but it's still pretty bad.  That's pretty much a given.

2.  I didn't even know the PS3 had pressure sensitive buttons-- that's how much they're used.  

3.  From the sounds of it, the few games that do use them don't use them well.  Even without people saying that I can still tell they're confusing to use.

4.  The PS3 controller is too light for me, it has no weight.

5.  The PS3 triggers are awful, as bad as the 360's D-Pad.  Luckily I rarely use the D-Pad but I use the triggers all the time.

6.  I have big hands so the spacing of the two analogue sticks on the PS3 controller is bad because my thumbs often hit each other.

So yeah, I much prefer the 360 controller.

Both are good. The Box controller feels more comfortable but the Dualshock looks cooler. And I don´t like the positioning of the left Analog Stick on the Xbox controller.

Ah, yes. The analog face buttons. The reason why I couldn't possibly do a consistent combo in The Bouncer. It had combos that required a soft, soft, hard press or something like that. When I tried it, the controller kept reading them wrong. This was included in Metal Gear Solid and it worked pretty well, though.

In Metal Gear, you hold the button down to shoot. Certain guns wouldn't actually shoot until you released the button (you could slowly release the button to put your weapon away, too). Other weapons would let you aim but wouldn't fire until you pressed the button hard.

Aside from that rare moment, I'm having a really hard time thinking of any game that would benefit from analog face buttons (since duration of a button press is what decided strength these days) or any game other than the Metal Gear games that ever did benefit.

In the end, it another thing that is different on one console that isn't on the other so we automatically make a big deal about it like it's a gamechanger. Nobody notices or even cares about that these days. It's almost like the Dual Shock 3 having built in motion controls. It's a non-issue.

You're doing it wrong. I think Fifa is by far the best example of pressure sensitive buttons used well.

Yeah they're not used often but Fifa is a good example of a game where the sensitivity of the buttons changes the gameplay. You use it for controlling the distance and speed of your shots, while also using the sensitivity of the anaolgue sticks to control the speed of the player. It really makes the game feel much more intuitive and realistic having the extra demension of control.

I much rather have the option then not, for me Fifa would not be the same without it.

The FPS and TPS genres are far more in demand then beat em ups, fighting games, and platformers. I mean really more in demand.

I'm not really trying to say they aren't worth having, but they're hardly the definitive reason the PS3 controller is better than the 360 controller like the OP mentions.

For me, the two biggest issues are the D-Pad on the 360 controller and the triggers on the PS3 controller.  The D-Pad really isn't used that much for games (and fighting games, where they're primarily used, a lot of people buy a seperate controller for anyways) or isn't used in a way where precision is really needed but most modern games use triggers.
