I've used 10's, 12's, 15's, and 18's and although I would love to do an 18 in the G, I'd rather not take up so much space so a 15 will do. I also like IB (infinite baffle) setups, even though I haven't had one myself, but heard several of them.

If I listened to rock I would do sealed. but I don't.

and the winner is...
it depends.
vented box :
1. generally will require more airspace
2. will have +3db of gain at ported frequency (i.e. twice as much output)
3. will not control excursion below ported frequency (sub will unload/bottom out)
4. will limit excursion at ported frequency
sealed box :
1. generally will produce more accurate bass
2. generally will not require as much airspace
3. generally will have flatter frequency response
4. generally will have longer excursion at most frequencies
A sealed box will give you better *extension* into the low frequencies, while a ported box will jam hard and then die off below its tuned freq... which is where some people get confused as to which is better for "low bass".
Box design is not independent of speaker selection or amp selection or install vehicle or musical taste.
With that said... I'm a fan of low-tuned ported boxes or sealed boxes with plenty of powa.
For awhile, I had a JL 12w3, JL 500/1 ported box tuned to 28 hz. That was a sweet setup
Then again I also had 600w to my front stage, so that helped.
