I've been putting together a new HT setup and considered all three of the speakers you mention. Here's my brief thoughts on all of them:
The Rockets are nice speakers, albeit it a bit laid back, but really the sole reason why I passed on them is the matching center channel. It's absolutely huge and would in no way fit on either shelf of my TV stand. That may sound trivial, but it was a deal breaker for me.
The 6.2 is from the "new" Swan line right? I've only heard the older Swan line-up and I hope they aren't still using the same piece of shit tweeter the older ones used. If they are using a different tweeter they might be worth checking out as I thought the original Swan's were a good bargain except for the tweeter.
I've heard a good bit of the Axiom line-up and have owned a pair of M22ti's for a few years now and I have always liked them for their detail and neutrality. However they can be very bright and that is the main reason why I didn't strongly consider getting a pair of their towers to use as my main speakers.
What I did end up getting are a pair of Quad 22L and the matching L-centre center channel. The 22L are a really nice sounding pair of speakers and the finish on them is stunning for the price. I'll post some pics when I get my camera back and I'll post more impressions in the near future.
