Yes that may be true. My buddy got a brand new TRS 9-46 for a used price so it was worth taking the plunge. He spent the $40 or so on a new chain and also measured it and the derailleur – which seems like it has a long enough cage – with the suspension fully extended to get the correct sizing. The 32T chainring he has is about right for the gearing and the 9 tooth works on his frame. All in all, it’s about a 35% savings (assuming the TRS cassette and chain were bought new) vs. going with a GX Eagle.
It’ll be interesting to see how it performs over the long-term and should determine whether the savings would be worth it.
