Unless you have the 64 bit XP (pretty rare, relatively), going 64bit is a plus.
FWIW I ran XPpro for the longest. I started Windows with W3.1, which also
supported my DOS networked devices (I later went Netware 4.2)
Now comes the differences in opinion

VISTA was a PITA (at least when I went upgrade from XPpro on my AMD Athelon)
To me, W7 did fix a lot of holes (I had used BSD at work) and it gave me Media Centre (HD TV recording).
I tried W8 while waiting for doors to be unlocked in the MS demo room. I HATE TILES. (UBUNTU went down that path

)
Then W10 undid some of the (perceived gains) by removing Media center and no longer having drivers for my older HW. At least W10 is stable.
My one foray into W11 was frustrating. They buried, moved or dumbed down the users ability to do much of the stuff we had been using since W3
Also, 7 Windows machines (Celeron, Core duo and i7, AMD) and NONE will pass the W11 HW check. And I can't even use the 32 bit HW as a Remote Desktop Connection TERMINAL (That was how I did my initial 900 Calibre entries of my Paper Library that was on My home office tower. REMOTE, not a share)
So as you can see, 900 users, 1000 opinions
