adobe Lightroom or adobe Lightroom classic?

Hello everyone,

I have used other software in the past for editing images, and have recently decided to use Adobe Lightroom.  I am confused though..  I am not concered about editing on the go, and want to do the most i possibly can with the program.  I am guessing that Lightroom Classic is more powerful than Lightroom as it is only available on desktop, or are they the exact same but one uses the cloud and the other doesnt?

I just want to be sure im using the right one.

Hopefully someone can cleart this up for me.

Regards

Richie.
