Many mfr seems to go from tm to mtm for their bigger and costlier loudspeakers, it almost seems to be the natural step, but what do you prefere, for your own creations, mtm or tm?
Well two drivers are obviously better than one if the amp and tweeter can keep up.A mtm setup would simplify the crossover and allow for a higher crossover than a tmm since the tweeter would be closer to both tweeters.Depends how much cost and size is an issue for you
Thats quite incorrect. MTM`s require lower crossover points which in turn require steeper functon due to lobbing issues on the vertical plane. Besides, the tweeter will be at the same distance from any of the woofer centres as in a TM configuration.
The main advantage of an MTM is a slimmer cabinet for the same woofer area, which allows a smaller footprint, and so (in principle, at least), a more domestically acceptable item.
Using a pair of smaller woofers, rather than a single larger one, also allows the centres of the mid bass drivers to be placed closer to the tweeter, as well as reducing the ratio of the dimensions between the drivers. Both of these should make for a smoother transition of the off-axis response at the crossover frequency.
It gives the designer the ability to alter the vertical polar pattern (the d'Appolito approach) to give more beaming towards the listener in the vertical plane, which some prefer and some don't.

It’s been my personal experience with over 30yrs of critical listening for a living as a live, production and recording engineer as well as a session player that a point source loudspeaker system produces the best experience.........and the farther away from a single point we go, the worse. When most of the phase anomolies are gone, it’s a revelation to the hidden details that were masked before.

So you favor tm over mtm?
