Due to the recessed mounting perch on the HD series, the 12HD has only slightly more hang height even though the driver is 2" larger in Dia., when comparing to a rev-10v2 with tube clamp to 12HD with 2 clamp.
No tower can produce bass. Mid-bass? Yes. The 10HD really isnt going to produce more mid-bass, as this is a product of the mid-bass driver size. Both are 10". The new HD pod is slightly larger in volume, v's the original rev, which will help with mid-bass extension. However, I think measurable difference would be inaudible in the wild. What does give the 10HD the appearance of producing more mid-bass, is the all new cross-over and compression driver. When you rain in and tone down the harsher frequencies, the drivers "seems" to produce more mid-bass. So all in all, the HD is a larger step in HLCD performance over the Rev v2 series.
Lets talk woofers, since they were mentioned. There is nothing magic that one brand can do to make their woofer hit, slam, pound, etc, harder then another. There are 4 real factors that effect output. driver size, enclosure, wattage supplied and the drivers excursion. The first 3, we as a consumer/installer can control. So, if two woofers are the same size, in the same enclosure type/size and supplied the same wattage, their output (choose your buzz word: hit slam pound) would be about the same. If you are comparing two woofers any one of the 3 previous factors is not the same between the two, its not the woofer's brands you are comparing, but rather the larger woofer to a smaller woofer, the one in a ported enclosure v's the one in the sealed or IB enclosure or the one thats fed more wattage.
XM9 to rev-10; Keep in mind, despite Brian's efforts to pass the xm9 off as a 9" driver, is was an 8". So comparing an 8" HLCD to a 10" HLCD is no comparison. Again, its not a brand thing. The rev-10 also had a slightly larger compression driver.
Class A/B amps can and will overheat on a boat, in July, when heavily loaded. Brian gave some bad advice by telling buyers to run the 6-pod hybrid setup at 1.5 ohm p/chnl on their 2 chnl amp, even though the amp was only intended for a minimum of a 2 ohm load p/chnl. Moving to the more efficient class-D amps is a move in the right direction to avoid thermal shutdown, but also knowing how to properly setup and tune any amp, is equally important.

Hard to put a finger on "better". However, 4 HLCDs, although smaller mid-bass drivers, will be louder then 2 larger HLCD. However, rule of thumb is that the larger driver will have deeper mid-bass. So a little better sound quality near field.
I have not heard the Rev-10HD yet, just the rev-10v2 v's the Rev-12HD when swapping out my v2's the 12HD.
