OP, how cold tolerant are you? What is your budget? Those are the two main questions you need to answer. If you can afford a drysuit, I would absolutely go that route. I did, and there is no way I would be diving locally as much as I do if I had to don a wetsuit. Everyone's tolerance for cold is different, but I would say I'm somewhere in the middle of the pack based on how I see other people react to water temps. In the summer, water temps at my local spots range between the mid-40s to the mid-60s at depth. I see people dive those conditions in double 7mm suits and they are generally pretty chilled after one dive when the water is at the colder end of the range. Most call it quits after a single dive, and only a few hardy souls are up for a short second dive. All of us drysuit divers, on the other hand, are fine.
I have the Scubapro Everdry, which is the same suit you are looking at but with neoprene seals. I bought it because I got it on a major discount. It's a good suit but it has some quirks, mostly to do with Scubapro's odd sizing. Scubapro models must all be tall and thin with narrow shoulders. By design, the suits tend to fit rather snugly. That's good if you are diving at the upper end of typical drysuit diving water temps, because you don't need a lot in the way of undergarments to stay comfortable, and the streamlined fit makes diving in them easy. They also take a lot less air to stave off suit squeeze, making buoyancy control much easier than in a traditional trilam suit. On the other hand, you will likely find that you have to size up at least one full size just to fit in one, and might need to go up several sizes if you intend to dive in colder water and require thicker undergarments. Length might then become a problem. Definitely try one on in person. This is always the way to go with any thermal protection, but I can't stress this enough with the Scubapro drysuits.
For what it's worth, I plan on ditching mine and getting something else this spring (maybe an Aqualung Fusion Bullet). I find that my suit is too snug to fit the thickness of undergarments I need for diving in the spring and late fall. It is also a bit too snug in the shoulders for my liking. It didn't bother me at first, but I don't have quite the shoulder mobility I would like and that can be dangerous. Back-zip is kinda getting annoying too, and I would prefer a self-donning suit. Lastly, I want dry gloves and, given my other issues with this suit, don't want to pay to have this one customized to accept them.
