A bit like "which oil?" but here is a different perspective:
I cringe when people say 'I live in a dry area so wet road grip isn't a priority'. I live in an ultra dry area but when it rains the accumulated oil/diesel+water is treacherously slick ,particularly on asphalt. If you use ultra high performance summer tires in such conditions - it will feel like you are on slicks. The Tire Rack test videos show the wet road test - it is just water -no oily/diesel residue. If you watch/compare the best wet road grip tires performance in the dry ,there is very little sacrifice . But the other way round ,the penalty can be severe.
The 'Spider Charts' at Tire Rack are useful to figure out the trade-offs:

For example, Yokohama had a slight edge in Dry but was a dud in the Wet. Pirelli P Zero was almost as good, in the Dry - but way,way better in Wet. YEMV
Fast+wet is when you'll need the best compromise, not fast+dry (for normal road driving)
