When I first started with IK products I bought the iRig UA 2015. I wanted a little bass amp emulator for my Android phone. That worked out well, I like the sound of the B15 on it (written in stone inside hardware - phone app is just to make adjustments).
I had always wanted the Miroslav collection since reading about it back when he created it (was fan of his bass playing in Mahavishnu Orchestra). I was amazed when I saw because I had bought the iRig UA that I could buy the full Miroslav 2 for $130 in 2017 as crossgrade with Jam Points.
Then because I'm frugal I went the Custom Shop route to buy SVX and Fender 1 so I had some decent amp sims for amps I would use.
Because of all the above steps I got to the IK Buyer 101 level. Over on the Cantabile forum I defended the confusing IK marketing as something you can sort out and if you wait for sales you can get the products at very affordable prices. I posted a link to this thread there calling it a college level course on the Group Buy
