Seat position is vital.
You can listen to all these different opinions and come up with many different answers.
I think its a personal thing, you found a height that worked for you, I suggest very strongly you go back to it.
It took me a while to find an ideal seat height on the different aircraft I have flown and it wasn't always what the manufacturer recommended.
As long as you can see everything you need to inside and out as well as operate all controls as required go with the height that works for you.
It is a big part of making consistently good landings.
