tor win32 vs win64

Hi there,
I wonder if there are any dis/advantages that Windows Expert Bundle is offered to download here http://2gzyxa5ihm7nsggfxnu52rck2vv4rvmdlkiu3zzui5du4xyclen53wid.onion/download/tor/as win32 version vs win64 that is also (hidden) available? Most of Windows machines are win64 nowadays, TorBrowser uses tor64 so is there any advantages/disadvantages that win32 should be used?
Happy New Year!
