I looked at both of those boats when I was searching for a boat. I can't comment on their sailing ability as I never sailed either, but I did take a lot of notes on the interiors. I found them both to be too small for my purposes (liveaboard).
When I looked at the listing for the Allied Princess, I expected to love it. The interior looked really great and spacious. When I actually saw it in person, I couldn't believe it was a 36' boat. It felt like a sardine can. The companionway stairs basically cut off access to the galley, the galley is too small to turn around in... a real shame. It also has rack and pinion steering, which I don't know the pros and cons of, but it makes for a very strange wheel location. The one I saw had no AC wiring. The one I saw had a bunch of holes cut in behind the settees for storage. My broker told me that was done custom, and on most of these that area is just dead space.
The Pearson 365 is still small, but it seems to have much more space inside. The interior looks very bland, almost institutional, but seems to be well-made. The model I saw had a separate shower stall in the head, which was a very nice feature, but since I'm 6'1", it was too short for me. The V-berth is also a bit short for me. Those size issues were the #1 dealbreaker for this boat. It has huge lazarettes and good access to the engine. The Pearson 36 mark 2 is a good bit more money, but about the same size, and has a fantastic interior and build quality, so you might want to look at one of those if you like Pearsons.
