In my humble opinion, when it's 1v1 with items, the items always drop closer to the person who is losing, unless it's something that will blow up. Granted there will be times that an item will drop by the winner that won't explode, but from my person experience, I have seen it almost always try to give the losing play some sort of edge when playing with items.
From what I've known from tournies around the US, I thought the loser picks the level. I thought only moving levels were restricted, and that the loser or new comer gets to pick the level. I just think that since everyone ussually is the same characters, due to character tier and popularity, that the same levels are always getting picked. I've seen a lot of interesting and fun 1v1, no item matches online and I really don't think the tournie style of playing is really that dull. You can actually learn a lot from watching them, and I don't mean wavedashing. Sure, A lot of tournies are won with the higher tier characters, but I have seen A LOT of videos and tournies won by Peach and Link. Lately, The Ice Climbers have been winning a lot of matches to, becuase of a new "glitch" that always you to have complete control over both characters, for the most part.
I personally can't do wavedashing effectively, and I do think it should be taken care of in Brawl. Although, I do see where it has now became an underground move, and seeing them make it an actual legit move in the game and making it easier to pull off for the sake of everyone. I don't fully agree with it, but I can still see it being thought about in development.
I really can't stand any new MK games, and DoA really never interested me either. I do love fighting games though, especially Soul Caliber titles, but I can't stand how newer fighting games just don't flow with each other. Mostly all the moves are kind of choppy, and I understand it's to stop people from button mashing, but the moves and combos don't really flow together in my opinion. SSBM is a very intense and smooth playing 1v1 game, and it really does show off the cream of your crops. When my friends and I get together to play Smash Brother Melee, we don't let each other use C-Sticking and we don't use items. Personally think items makes some people cowards and sit at the end of the screen and constantly running around from people until they get an item. A good example is having Samus sit at one end of Hyrule Castle, and constantly using ranged attacks until an item falls by them to come into a battle. Don't get me wrong, we play with items here and there, but showing off your raw skills and not having to deal with trying to organize and control the chaos around you is really fun. Situations like this, your every move is vital and the slightest bit of hestitation can cost you a life. You can also really find your weakness with a certain character doing 1v1 and improve your game a lot just in that respect.
It's still an epic battle that is chaotic, fast paced, and intense. I also think throwing and short jumps becomes more insential with no items, but this is just my opinion and don't really expect to change other peoples minds about how to play the game. I support 4 player items all the way, but I also understand the depth of 1v1 in Melee. I just fully support the 1v1, no items tournies and think it opens another element to the game that most people don't see for themselves. Everyone has their own style and way of playing the game, and in the end, I would like to see every option and way of playing the game open to everyone, even in the tournies.
