Temensis are a beautiful cichla regardless of collection point. The problem other than the obvious size attained, is they do not start showing colors until 20"+. To get to that point takes a lot of tank space, food, and dedication. Many of us have a no patience mentality and want the instant gratification. Its not going to happen with a Tem. Most of the other Cichla sp. start coloring up at 6"+, and while it may be slow to reach full potential...you are atleast slowly rewarded and keeps you motivated.
My Tems were 20-23" at time of separation. My tank had very basic lighting so these pics Do not reflect their colors accurately. You can see glimpses in various pics of what their true colors. Stripes would vary from a drab black to full on dark black depending on mood. Red was strong in tail, and the yellow was really starting to come through. The areas that may appear grayish were actually a beige color. This was the brown color transitioning into Aduly coloration. They were about 3 yrs old if I recall, and I had them since 4".
Heres a thread I posted on them -

The RN Tems Have much stronger coloration throughout, and are said to attain a larger size than most Tems.
Temensis are a beautiful fish for aquaria, but require the dedication, and space.
Here is a pic of a 'Reg' Tem Which I think is beautiful.-
As for Tems being better looking than FOGO, all in the eye of the beholder. There are qualities unique to each species to be admired.
Also...a few more RN Tems -
