Windows or Chrome? Mem/Resource Usage

Windows or Chrome? Mem/Resource Usage

Hi All!  Relatively new user of Nimbus.  I'm on a PC w/Win10.  I also favor Chrome as my browser.

My question is this:  Which Nimbus method should I use for best PC Performance/Least resource hoggery?

1)  Nimbus on Web in Chrome or 
2)  Nimbus standalone program in Windows.

Thanks for any responses!
