My experience is with Discatcher Sport, M-14, Tri-State (ugh), Skillshot, & Traveler.
As others have said, it all depends on how you're going to use it.
If you're talking about a putting practice basket for your yard, to be left out or hauled a short distance, I like the Sport. Add extra chains, and you've almost got a regular basket. Though if you're leaving it out, among mine the M-14s weathered better than the Sports, which have rusted in places.
If you're throwing it in your car to haul down to a local park, it's a different story. Personally, I like the Traveler just because of the net. Dead-on, center-chain putts stay in instead of cutting through. The target area is smaller than normal baskets, so it improves your aim. The odd square basket doesn't matter to me, because I'm not aiming for it anyway. And I'm trying to improve, not score. But you can't leave it out, and it will topple in high winds since it's so light.
