Should I play 64-bit or 32-bit?

[Puddle Jumper]

After many months of not playing KSP I'm about to pick it up again. To my surprise I see I have the option of choosing between 32-bit and 64-bit. What should I choose to get the best experience possible? I play on a modern pc with 64-bit Windows 10. I thought I heared that 64-bit is advantageous when using mods, but I use no mods whatsoever.

Have 64bit CPU & OS: Use 64bit version - there's no good reason not to and it allows the game to use more memory (probably not a big deal with stock, but much important with mods).

The whole mods not supporting 64-bit is a thing of the past, when KSP 64-bit first came out. That version was so unstable that even the stock game had problems. But the 64-bit version has been redone and should work perfectly fine in stock.
