Not sure about brands, but the formulation makes a difference.

For long term durability you want a penetrating oil, not “waterproofing” like Thompson.

Been using Flood, CWF-UV since my deck was new. Still looks great after 25 years

I’m a big fan of Penofin.
I used the Austrian timber oil last time as it was on sale but I won’t be using it again. I only got one season out of it and what is left will need to be stripped off now.

guess I had better luck, mine doesn't look too bad after 4 years, a bit of mildew this year with all the rain.

Cash in that retirement and go with one of the Trex type of boards. We eliminated our deck and went to a cement patio about 10 years ago. Build a 4’ x 10’ ”deck” with stairs to get to the patio. The trex boards still look new.
