My favorite is my SP-01. I have owned it the longest and use it in IDPA so I've shot it the most as well. But, I really do like my P-09 as well especially given the price. I got mine used for a good price and even after I added some CGW parts it came out to around the same price as my stock SP-01 I bought new. My SP-01 is very far from stock now and has a better trigger than the P-09, but the P-09 is great in the price vs. performance area.
I loved CZ's since I bought my first CZ a few years ago. I now own 6 CZ's plus a CZ Clone as well. I also own Glocks, S&W M&P, BHP, and others, but my favorites are my CZ's. It might be because I haven't found holsters that I like yet, but I tend to not carry my CZ's. My carry guns usually are a G26 or S&W Shield, but I'm typing this carrying my CZ Clone, Sphinx SDP Compact in a IWB Bladetech holster.
