The Dewalt 780 is a great mitersaw but if you want to put the saw right up against the wall I would definitely go with the Bosch glide system also if you looking for a budget friendly saw I would recommend the Ridgid miter is pretty good
i have a Dewalt miter and have no complaints ive also used Milwaukee and Mikita miter saws and I don't like the Mikita compared to the Milwaukee and Dewalt and between the Milwaukee and Dewalt I like the Dewalt better it might just be what I'm used to
to but you can't go wrong with any major brand
