Francesco,
Your experience and mine are very similar, although I haven't at it near as long. I started LF with a 4x5. Not having a 4x5 enlarger at the time, I was contact printing on enlarging paper. One thing led to another and a few months later I had the 8x10 (plus a borrowed 4x5 enlarger). The 8x10 just is a joy to work with. There's no squinting down to see the image. That problem even existed with the 4x5. For once, I felt like I was really studying the image, like I can see every square millimeter of it. That for me is the real joy. The image comes out just like I saw it on the ground glass. And the ground glass doesn't lie.
