It is great to see such enthusiasm for Haydn's sonatas! I have the Vienna Urtext Edition of them and am pretty sure they are chronologically arranged. I play them all regularly.
I can´t stand Clementi.
I don't know what possessed me to pick-up a book of Clementi Sonatas from the library the other day but yesterday I started playing one (op.36?)...
it felt like I was slipping into a coma. Anyway, I abandoned it part way and quickly reached for Haydn Sonatas vol. 1 and played the first 6 sonatas to purge myself.
I've heard some of Bredel's recordings of Haydn and like them.
Is anyone aware of any recordings of Haydn Sonatas played on a Fortepiano?
