I've got tons of keyboards as well, and despite just weeks ago getting the new Wooting keyboard am likely to get another. You don't really know if you like a board until you use it for a while.
Like, I thought the near-TKL design of the Wooting would be fine, but it's actually incredibly annoying. I often use delete, home, end, page up, and page down[1] but only 4 of the keys exist in that cluster. Why could they not have just added the tiny bit of extra width to include the rest of the cluster?
On other boards the issues that made me try something else tended to come down to the switches. It's wild how some switches were so easy to press that the weight of my fingers was basically enough to actuate them, while others made my fingers feel tired when trying to overcome the resistance of the tactile bump. I had one board I could hot swap keys on which made it easy to try other kinds but I gave up on doing that since even when I thought they were well aligned I would bend pins when pushing them in (and bending them back would just break the pins off, leading to many trashed switches).
