I can offer only general advice, since my hands-on experience is only with the (modified) Harris.  I suggest, as the owner of a valuable Supermatch, that you carefully eval the various units, hands-on, and hang the expense.  There's really not a lot of diff, all things considered.
Every time I've made a bad purchase, it's always been because I've unwisely "cheaped-out" and bought something "nearly as good" only to find that the item was not so.
I've never yet had the opportunity to regret buying top quality, and I expect I never will.
Buy the best appropriate item for your intended use.  You'll never regret it.
