I too am like Maytom. I start them out, or float call with a friction call, usually a glass pot call called The MOJO by River Valley, it offers me both slate and glass but if I'm alone I'll obviously switch to the mouth call to get them in tight. If I'm calling for someone else and can keep my hands free and clear from sight, I'll keep at em with the glass/friction call and throw in a couple calls from the mouth call. If it's the mouth call they respond to, I'll use it.
You need to take the turkeys temperature with a variety of calls. He might respond better to one call or another but to stay 90% with one call, one might miss out on a lot of opportunities. Perhaps it's the box call that will have them screaming in when the mouth or pot call only temps them....or vise versa....I never rely on one call alone, that's why my turkey vest weighs too much.
As for options on another manuf mouth call, try River Valley Game Calls' mouth calls. They tend to be smaller than most on the market therefore fitting the majority of small pallets amoung us hunters. There is less need to trim them as they use the smaller frames....Of course there are many, many quality mouth calls on the market and if your fluent with a mouth call, you'll get quality sound from all...some you'll like better than others....
