I only used Miami once in my life when setting up my old Α600 with 030. It was not such a pleasant experience being rather slow for my taste. Once I reformated and setup AmiTCP over classic wb, everything was running very smoothly and quick (using no GUI though but declarations in User-Startup OR batch files if you didn't want on startup).
Installation for WiFi was not so difficult but needed some alteration on config files by hand to run just fine 
Apart from that I'm using Genesis ever since since all my Amigas have 3.9 on them and it works like a charm
Good luck in everything you try.
MiamiDX runs fantastic on my machine which is just a 030/40/32MB with classicWB ADV
