QuoteThe 2019 iMac, particularly the 21.5 inch 4K retina model is a surprisingly great value. Just don't buy the base model!

The higher price model is a lot better. 

Best Apple's Desktop:
1. iMac 4k.
2. Mac mini.
3. iMac 5k.
4. Mac pro.
5. iMac pro.

1.24n iMac
2. MacBook Air
3.  iMac (27-inch, 2020)

I vote for the Mac Plus https://en.wikipedia.org/wiki/Macintosh_Plus

mostly because it could run this game https://www.youtube.com/watch?v=mCY_OrFddEc

and because it ran HyperCard, the best app ever made https://www.youtube.com/watch?v=tx_WCIAM4bA
