The sales staff are all trained in 30 year old psychology tricks to make you think you're getting a good deal and make you feel more invested in the process than you actually are. I wouldn't call them pushy (and they seem to vary widely) but some of them are downright rude. For a place that boasts 10'000 suits they present preciously few actual options on top of which, everything takes forever to fetch.
They do have a large selection and they do seem to have a lot at lower price points so maybe if you're on a tight budget you'd fare better here than elsewhere. But if you're looking to get a good suit you can almost certainly do better with a department store and a good tailor or one of the cheaper made-to-order places.
