In reply to humptydumpty: solid gates are easier to make without the notch to keep the wire gate in place, maybe makes them easier to clip into bolts perhaps? Good compromise is something like the helium, it has a shroud to stop it snagging.
Big, easy to grab bent solid gates are nice to clip. Bash the spine of a solid gate against the palm of your hand, then try it with a wire gate, whilst rare it's not unheard of for this whiplash to unclip the rope.
Wire gates all the way for me, light as possible for trad/long routes. You might do well to get larger/burlier carabiner for sport - easier to clip and more resistant to getting mashed up on the bolt end. If not just figure out where you're going to use it most or find a compromise you're happy with.
If you do any winter climbing go with wire gates, as mentioned before solid gates freeze up
