For what its worth here is a newbies take on a new wetsuit.
My partner and I each had a Seaquel semidry custom fitted. We had compared the main brands and found that the Seaquel was a fair bit cheaper, seemed to be great quality and had the bonus of being custom fitted.
We are very much novice divers having a grand total of 6 dives after our trip to the Poor Knights. Firstly I can't recommend Yukon Dive enough. They took very good care of us, helped us with setting up our gear, answered our many questions, and then looked after us in the water.
The wetsuits, from our limited experience point of view, seemed to work very well. The first thing we noticed was how easy our suits were to get on compared to some of the others on the boat. In particular another diver wore a Mares suit that we had looked at buying. It took them quite some time to get it on, really seemed to be quite difficult. Ours in comparison were a breeze with the long zip down to the thigh. One thing I did notice was that with the suit only half on it did want to sit very low. Tried to zip it up a little but it kept dropping down. Just something to get used to. Getting it on was definitely a solo job.
The boots and gloves, also Seaquel, went on fine. My partner wore a hood which fitted great. The hood she had used during training would ride back on her head, but this one stayed where it was meant to the whole time. I liked the cuffs on the suit that you fold back under themselves to create a seal, seemed to work well and was comfy with the gloves.
The suit is nice and tight once on so there wasn't much of a rush of water when we jumped in. The suit didn't move around at all once in the water. Being a 7mm I thought it might restrict my movement a little, but it seemed very flexible. Im also realising that you don't tend to move around much underwater anyway! Our dives lasted around 45 mins or so. The water was relatively cool, less than 20 at the surface and dropping quite quickly with depth. We never felt it. There were a few comments when we got back on board from some of the others but we had been quite toasty. I only got a feeling for the temp when I jumped in for a swim having taken all my gear off. That lasted about 30 secs before I made a dash for the transom shower!
Getting the suits off was easy, though we did need a hand to pull an arm out of the sleeve. Once one was free we could manage ourselves. We kept the suits half on between dives, getting the top back on wasn't a problem.
I did notice that my suit had a small patch of wear on the upper chest towards the shoulder. Im guessing its from the shoulder strap. Nothing drastic, just cosmetic and pretty small.
Overall we are very happy with the suits, they were easy to get on and off, fitted very well and were warm.
As an aside there were a couple of downsides to the dives. My Mares essence mask just wouldn't seal. I continually had water coming in and so spent all my time trying to clear it. I talked it through with the instructors on board between dives and we decided that I should loosen it up. This helped a little but it still wasn't great. Im also struggling with clearing my ears. Im a pilot and so know plenty of techniques for clearing sinuses from my flying but it just wasn't working for me. It was a continual effort to clear my ears, not at all an automatic function like it is when I fly. Hopefully I get the hang of it because it really detracted from the diving.
Well thats my take on the Seaquel semidry anyway. I would not hesitate to recommend them, and in particular Clinton at the shop.
