If I go TG6, I am going to want to upgrade right away. For those posting content, unless you are posting full resolution, it isn't telling me anything technical about the camera. Every full resolution TG6 picture lacks detail - pictures look like they either didn't focus sharply, or someone ran aggressive noise removal. I do think this would have been a better option than the GoPro for people to have recommended for my first trip.
The biggest advantage of the g7x is the amount of quality underwater images. I know I'd be happy with this camera for many years.
That PEN E-PL10 is exactly what I want on paper and not much more money. It seems like the base model is better than the g7x and lens options give me a lot more room to upgrade in the future. But I can't find a single underwater image. I think I'd be happy with this above water too.
RX100 seems like a little more money than a g7x for the same quality but more lens options.
Not sure how much it matters, but the RX100 and g7x seem like a big step up from the gopro for video, while the E-PL10 video might be a step back.
Everyone tells me brightness of my strobe is what limits my sensor size. What does anyone think about a single Z330? That is $650 and one of the brighter strobes and I'd think it was enough for anything. Backscatter also has a Kraken KR-S02 used for $400. The Inon S2000 seems like the best budget choice at $365. A $285 difference from the cheapest budget strobe to the brightest doesn't seem to fit with everyone telling me not to go DSLR unless I am willing to invest heavily.
Any other strobes to consider?
Does everyone with 2 strobes use the same kind? I'd think a pair mismatched strobes, if anything noticeable, would provide better images. But everyone I remember diving with multiple strobes had 2 of the same. It matters, because if I buy a single S2000, my next upgrade has to be a 2nd S2000, and if I upgrade further, I have to replace both.
You may not find much from the PEN model but the EM-5 II and EM-10 II and III have the same sensor and you'll find lots of images from them around, with the 14-42 and other lenses. Here's a leafy shot with an EM-5II and 12-40 lens:

The 24-70 is the most universal lens option for the 1"compacts. I suspect you'll want at least a wide lens for that camera - you probably won't want to spend the price of the housing plus camera for a WWL which would be the ultimate image quality, so I guess you be looking at something like the INON lens I linked earlier - you can also add a dome to that to get a 150° field of view.
regarding strobes if you went with the G7X I would suggest two S2000 strobes rather than a single Z-330. The bigger sensor on the EPL10 model you would probably shoot 1 stop down so the S-2000s would be borderline there but likely workable. I use Z-240 strobes 9old model from Z330) and they gain about 1/2 stop over the S2000. It depends on whether you think you'll want the extra setup and carrying of having two strobes or not. I wouldn't suggest the Kraken it seems an odd combination and I haven't heard of too many people using them.
lastly if you are doing any video without lights the G7X will be better at white balancing, compared to the SONY cameras.
