Tom, as you know I can’t comment on sound or DCC aspects. And I understand some users, especially DCC users, have had issues with the incandesent lamps.
All that said, my two sets of Genesis F units run great, and look great, by far the best in terms of detail. As for quality control issues, I have none - But, to be fair, one of my sets was built by me - undecorated Highliners kits.
The other set, WESTERN MARYLAND, was perfect out of the box, no issues.
I will say without question I consider my Intermountain F units every bit as nice, even if some of the detail is not quite as fine. Only noticeable difference, the LED lighing on the Intermountain is not as nice looking as the incandesents on the Genesis.
So far, running DC, I have had no issues with the Genesis lamps.
I actually have more Intermoutain units than Genesis because the ATLANTIC CENTRAL took a liking to FP7’s…Intermountain has undecorated FP7 kits.
Proto, the unit is very nice detail wise, I have one set in C&O. But I’m not thrilled with the slower gearing…and I sold off an undecorated set because they came with 1960’s modernized shells - I model 1954…Walthers had no “as built” shells to give or sell…
Personally, I don’t think you can go wrong any of those three brands when it comes to F units.
And, again, I will repeat my view. You cannot judge any of these companies based on one or two problematic products.
Those RS units were revised tooling that came from Model Die Casting, they were not made in the same factory as the Genesis F units, one has nothing to do with the other in terms of actual manufacturing.
I would doubt if there is even one common part, except maybe the couplers, between the two.
With all this stuff made by outside venders on the otherside of the globe, brand means very little. Each product, each set of tooling, each Chinese factory stand on its own as either good or bad.
