On M-: -- My typical approach is to use the scratch buffer, where I can evaluate multiple things and remember the outcomes, macroexpand etc. So, M-: isn't the only alternative to IELM, but there are also things that scratch doesn't work well with, especially when it comes to figuring out what current buffer is, saving point position, debugging, probably more. So, yeah, for more serious stuff, IELM is better.
