I love my rl-p!!! I honestly couldn't tell you if it is better than an avalanche or a XXX, but I can guarantee you will not be dissappointed with it as long as you do a proper install. Im sure the avalanche or XXX would sound great as well. I was in the same situation as you not to long and what I did was think of the pros and cons of each woofer. I came up with something similar to this.
Rl-p
PROS
- efficient
-works well in small box
- cheapest of the bunch
- looks so sexy
- best customer service on behalf of ss
CONS
- No xbl^2 (who cares?)
- Slightly less output potential than XXX
XXX
PROS
- greatest xmax
- greatest power handling
- greatest output potential
CONS
- Price ($450 in my case)
- needs tons of power (not so much of a problem in my case, but the strain you are putting onoyur alt is important
- large box size
AVALANCHE
PROS
- efficient
- price is mediocre
- positive reviews
CONS
- medium large box necessary
- less output potential than xxx
- looks (Im not a fan of the ava looks but thats just me)
In my eyes the rl-p was the clear winner, but it's different for everyone.
