I finally got the DaYan GuHong Pro 54mm. Here is my review of it along with the RS3M V5
DaYan GuHong Pro 54mm
First thoughts, the magnets felt weaker than what I am used to, so that made me have a negative first feel of the cube. I like stronger magnet for OH, so when I first tried it I was not liking the feeling. After some tensioning and lubes I have changed my feelings though. It still feels a little bit unstable and that causes me to get bad lockups, but that may just be due to a lack of experience with the cube. The smaller size definitely does feel a lot better during OH. It makes it easier to do some of the finger tricks, M slices also are easy and they feel nice to execute. I would say that out of the box the cube isn't particularly great, but after setup and break in the cube gets significantly better. I can barely feel the ball core in this cube, but I'm sure that it helps with the stability of the cube.

@Arcanist I would say that the cube is worth getting for OH, the smaller size makes a noticeable difference and I like it. The performance gets great with setup, but if you can't perform as well with weaker magnets, then that may be a downside to getting it.
RS3M V5
The cube feels nice out of the box, the ball core is strong and I can feel it in each turn. The magnets are a bit weak for me though, but with the stronger ball core I would say that the weaker magnets are not as big of an issue like in the GuHong. After setup and break in the cube got better and I was getting multiple sub 10 solves, along with some 8's. I would say that I currently lack consistency on it, but I'm sure that it is just a lack of experience again. I'm still not sure it if is better than the YS3M, which is my current main, so I would say if you have a YS3M then that will do just fine and this isn't a big upgrade, if any. It comes with a robot stand though, which is fun.
I also got the new fz lubes and they have not disappointed me, they are quite effective and I like them a lot. I also got some Adheron and I love how much you get for the cost, the bottle is 20ml for only 4 USD, very cost effective.
That is pretty much it for my reviews and I am overall very pleased with what I got. I will continue to use the GuHong for OH and the V5 for 3x3, and I will make another update in a couple days and share how the cubes are after hundreds of solves of break in.
