I have Bare Reactive in 3 and 5mm (old version - actually, just sold the 5mm a couple of weeks ago). I replaced the 5mm with a Waterproof W7 5mm.
After seeing my W7, one of our shop customers ordered the same. He was previously diving a Henderson Thermaxx 5mm.
After a weekend of diving in his new W7, he sought me out to tell me how much nicer he feels like the W7 is than his Thermaxx suit. His words were something like "a whole other level of quality, compared to the Henderson."
I have not dived a Thermaxx, but my old shop and my current shop sold/sell them. They have never FELT to me like they were the same level of quality as the Bare Reactives I've been diving.
I really don't have any experience whatsoever with the Aqualock. Looking at the way it "mates" to boots/gloves/etc, that looks just like the way the Reactive and W7 are setup. Except, the Reactive has ankle zips and the W7 has ankle and wrist zips. Personally, I think the zips help make the suit easier to get on.
The smoothskin surfaces at the wrists and ankles mate up to smoothskin on the inside of boots and gloves. The Waterproof G1 gloves have that same smoothskin on the whole inside of the gauntlet portions. The zippers at the wrists on the W7 suit makes it very easy to put the suit on, put the gloves on and get the sealing surfaces mated together, and then get the over-sleeve part in place. The Henderson having no zips at the wrist or ankle seems like it would make it a huge pain in the butt to get gloves mated to wrist seals and then the over-sleeve part in place over the gloves. The Bare Ultrawarmth gloves only have a narrow strip of smoothskin on the inside, that is right where the wrist area transitions to the hand. The Bare gloves are much more of a pain to put on than the Waterproof gloves. No idea on how easy or well Henderson gloves would go on and seal up to the wrist seals.
The new Reactive is claimed to be "30% warmer" than the old version. The old version is definitely a warm suit. I'm sure it as warm as a cheap 7mm. Of course, it is not as warm as a 7mm Reactive, so that claim about being the same as an unspecified 7mm is pure weaksauce.
I sold my Reactive 5mm because I got the W7 5mm. I think the W7 is as warm. At least, as warm as the old version of the Reactive. The W7 definitely has better seals at the wrists and ankles. And the W7 has very handy pockets. The Aqualock looks good, but no zippers on wrists or ankles would put me off it.
