I liked the UTEC, but I also like Osiris. My $0.02:
UTEC pros:
- Easy to tune/tweak AFR and timing maps.
- Knock sensitivity settings are adjustable, along with timing retard step/duration
UTEC cons:
- Need UTEC tuner to read AFR, and tuner requires welding additional bung/O2 sensor.
- Timing maps need corrections at different temps. Factory ECU has algorithm to determine timing based on environmental variables. Since UTEC overrides factory timing, adjusting timing temp corrections is time-consuming
Osiris pros (assuming user-tuneable version):
- Can tweak in real time, and 'trace' your pulls on the AFR matrix, so you know which cells to change
- Cipher can bump timing 2 degrees across the board
- Can log AFR from factory O2 sensors (through OBD2 port), along with dozens of other parameters
- 5 maps can be stored on your factory ECU, and changed with the cruise control switches
- Can tweak Electronic Throttle Control settings and Cam Advance
Osiris cons:
- A little more difficult to tune in AFR
- Timing not in degrees, but in 'burn time' -- more difficult to adjust
- Knock sensitivity not adjustable, and timing retard (during knock) doesn't work anywhere near as well as UTEC
- Have to reflash your ECU every time you want to make permanent changes

As you can tell I have no fricken idea what Im talking about. LOL
H8bumps knows his stuff, I would take his opinions into consideration and just call some of the vendors or other reputable Z shops.
It all depends on what you are doing to the car.
