Nice achievement
I personally think the best version is the Zero W followed by the 3b+
I have the 3b running pihole DNS, mysql and apache for home monitoring temps etc. The zero is in the garden solar powered with a 12v battery and controls the water feature (it's not a pond, I'm lot allowed one of them :) pumps and heaters to keep the fishies happy. It was fun setting it all up for under £100, kept me occupied for several days while on furlough:)
