I went from;
Blue Plus to Super Blue (close enough for me)
Fiji Pink to Fiji Purple (don't care)
Aquablue Special to Coral Light II new gen (from 15K to 14K)
All are minimal differences in spectrum
The Coral Light you mentioned is a 10K bulb and looks yellow to the eye, but is a very bright white in your tank and would be a good replacement for one of your gen II bulbs
If you're not growing show corals, or trying to make a living with them, you'll be fine with either brand
Just don't change all your bulbs at the same time
Do it over weeks per pair so your corals can adjust

Here's a small fight about it

Honestly, PARs cannot be compared between different people's value since ballast, reflector and the operating temperatures are variable. I tried finding the numbers but couldn't. Sanjay's reef lighting guide doesn't include T5. Don't know why he didn't look into it
