Samsung Galaxy Ultra vs Samsung Galaxy 6 Classic. Concerned I purchased the wrong watch, Thoughts?

I have been debating on get one of these two. I recently purchased the ultra. However, I find the screen rotating through tiles sometimes touchy, inaccurate, and having your finger block the screen kind of annoying.
I was wondering if anyone else has noticed this or any other issues with the watch.

I would have really liked having the bezel but the improved sensing and said speed of use made it seem like that better option.

I would enjoy hearing how others find the galaxy classic 6 and ultra themselves.

Thank you for any additional information!
