The numbering scheme really confuses you, isn't it ?
At one time,
CG3 = EQ2
CG4 = EQ3 (or EQ3-2)
CG5 = EQ4
This did not play too well, since few people compare mounts capacity just by numbers .
So later EQ4 magically morphed into EQ5 with minor changes (e.g., tripod leg size). I.e., EQ5 roughly equals to EQ4. But the mount head came from the same heritage.
After the successful CG5/EQ5 product, a new product line was introduced: EQ6/Atlas.
Then a new mount was produced somewhere in between EQ5 and EQ6 (closer to EQ6 than to EQ5). Now there is a problem, what should we call it? EQ5.5, baby-EQ6, EQ6-jr, EQ5-sr, NEQ5, LEQ6, ... . Now you can guess what it called today.
HEQ5 shares a lot of EQ6 design but is smaller.
EQ-G non-GOTO version of the HEQ5 still has the same intelligent motor controller, hybrid stepper-motors, and is EQMOD ready.

Although I do like the idea of quieter slewing motors!

EQ6 IMHO has quite a few design advantages over CG5/EQ4/EQ5.
The junior is a scaled version of EQ6 to make it lighter (some like this easier grab-n-go idea) but with less load carrying capability.
I think HEQ5's tripod steel tube diameter might be too small, which does not go together with the name HEQ5. Hopefully factory will correct it.
P.S. price is dependent to product volume.
My statement is based on technical merit, not price/performance consumer-report style scoring.

One difference between mine and a "stock" setup. I had a Meade Field Tripod that had a machinest friend make an adaptor plate so the head fits that tripod. I am happy with the set up. Yes, it twangs a little when you touch it to focus with a 6mm eyepiece, but it calms down in 5-8 seconds. I can live with that.
Clear skies to us all;
