I'd be prone to want to buy from the dealer with speakers that sound good to you that helps to best take your specific needs into consideration, including room size, acoustics, listening preferences, etc. That's probably the most important thing.
IF they focus too much on their product simply being "the best", beware, especially if there is more $$$$$s involved.
Dealers that focus exclusively on very expensive gear often tend to think that way. Otherwise, the $$$$s would not be justified. I tend to prefer dealers that try to offer the best gear possible at various price points. For a small room like that, Bigger + more expensive is less likely to translate into best results.
