You're asking us what kind of frets and fretboard radius you would like? That is all very personal, and you also need to consider the neck dimensions and nut size.
I love the feel of a 9.5" fretboard. My Tele has a 9.5" radius fretboard with narrow tall frets (6105), and a 1.65" nut. The neck shape is what the custom shop calls a 60's oval C. It is one of the most comfortable necks I have ever played on, and one of the main reasons I bought that extremely expensive guitar. To this day, I marvel at the feel. Granted, it is a custom shop guitar and the fretwork/fretboard work was obviously given the attention one should expect from a custom shop guitar.
My Lester has a 12" fretboard, medium jumbo frets, and about a 1.69" nut. It is an '02 LP 50's Standard Plus. I generally don't like "50's" necks, but this one is slightly thinner than any other 50's neck I have played. It fits so comfortably in my hand and is also one of the best feeling necks I have ever played. If I had just read it was a "50's" spec Les Paul online, I would have never bought it. However, I found it used at a Guitar Center, and fell in love with it.
Point is, only you know if the neck is perfect for you.
From what I have read, small radius fretboards can start to fret out, if they are not properly built or setup.
