I don't think that many people here hate Luxire or Eidos. Hating suggests one has to care enough about it to formulate hate. Well
Sartodinapoli hates Luxire.
If there is hate/dislike it stems from - as usually is the case - the uninformed making uninformed decisions and ending up with ill-fitting and or I'll-thought out shirts etc.
For someone who is looking for a cost-effective factory MTM shirt, go for it. As you have said you cannot find other MTO or bespoke in the same price range.
Same for Eidos. Coronating a new brand the next big thing as SF does leads to noobs and knobs jumping in on the uptake without figuring out if it works for their size/shape.
Again, if it works for you fit-wise and cost-wise who am I to say good or bad.
The one thing you will find here as opposed to SF is that none of the members that do bespoke, or MTM for that matter, pimp their particular makers much or at all. They speak of them in general terms within the context of what they like and what they get out of the interaction with the tailors. Which - other than being pleased with the shirt or suit - someone does not get directly from Luxire or Eidos. But that May not be important for some
