I run 14k. These may not be the hottest but they are some that I like under the 14k day and also blues at night:
BB Draw Jopper. Mines still pretty small but I'm really looking forward to it growing out. Has great color under MH.
RRC Shazam - I have a knock off piece, I believe it's the same just not from RR. Very cool coral.
TCK Supersonic - still kinda new but amazing blue under in the bag under daylight. Granted the base color is brown in 14k, the blues are so intense it looks false . It has multi tone polyps under all blue, like their picture.
RRC Hellfire Enchinata is great for lower in the tank acro - dominant tanks. Mine is higher, so not much orange but I'm happy with it.
Stags - Hugos rainbow stag and TGC Creamsicle are very nice day and night.
If you need a RED piece, CB Maleficent is hard to compete with
