We have the hayward colorlogic lights LED. 2 of them in a 16x34 dark vinyl lined pool. We really like them, especially with the choice of programs you can run. One note, it appears as more of a glow in our pool, we like it but if you really want something that is really bright, then go for non LED, unless you have a light colour vinyl/plaster. We were looking at the SAM lights too which use a color wheel that rotates in front of the LED. The Colorlogics use multiple coloured LED's to achieve the effect.
