Well from lvls 1-5 summoning animals while fighting with a spiked shillelagh and having a companion that fights as well as many of the PCs really rocks. At 5+ Wild shape takes over and the druid is an awesome tank, plus they are a full caster. Besides all this, they are almost entirely dependent on one high ability score (although having other high scores is always nice). Druids rock. Period.

To help with the original question, I don't think Gestalt is too much of a problem, but I'd be more hesitant to recommend it than some of the people here. I'm running two modified rules gestalt games at the moment (you can see the characters here and here), plus I've run a few in real life and I currently play in one (ya, I'm a junky).
To be perfectly honest though, I do usually find gestalt characters to be more powerful than other characters by a large degree. This really depends though on how good the players are at using synergy in building their characters. For instance, there are a ton of ways out there to add CHA to various things (saves, AC, HP, AC, saves, attack, damage, saves, AC, etc. ), so a character doubling up on classes that benefit from CHA can actually become more than twice as effective in a Gestalt game (just an example since this goes for other abilities as well).
The bottom line, IMO, is that Gestalt won't hurt your game too much if you think the players are generally equally skillful at building characters. If you have a few number crunchers in the game they will benefit far more from the options presented by gestalt than the guys in the group saying, "Wow, I can play a rogue/fighter combo!"
