Everybody seems to have a preference for transmissions. Which one is most popular and which do you prefer?

Automatics are close to Idiot proof, but are slow to get going.

I tried one and it took so long to really get moving it would be no good for crossing a highway from a standing start in heavy traffic

If you live or drive in mostly mountainous conditions, a 13 gear is what you want. If you're still new, start there and work your way up to 18. Keep in mind that you don't need 18 gears to get you through Nebraska, but they come in handy in Idaho during January.

Most companies these days, from what I hear, train with a 9 speed.

All I have is a Dodge Ram and that's all I need for now. I studied up on this when I was younger and wanted to long haul, but I chose a different career. You wonder how things would have went if you chose a different career, you know?

The industry seems to be going with auto-shift, which is not fully automatic. Before this became popular, the industry was mostly 10's, super 10's and 9 speeds. I prefer a 13 speed over anyting, but an 18 can be nice to have for the bottom low side.

A a small fleet owner, I've switched over to all autoshifts. As mentioned before they are idiot proof but they also NEVER miss a shift, NEVER smoke a clutch, NEVER twist out a driveshaft, NEVER strip a gear. Clutches last twice as long since they shift in milliseconds. All of them have 3 modes, economy, performance and manual. Most of the large fleets disable the performance and manual modes as a fuel saving measure, which can amount to millions of dollars for them. I leave it up to the drivers of my trucks, as an incentive to use economy mode I have a fuel bonus program. In performance mode they will spin the tires bobtail or with a light load. When heavy, performance mode will out accelerate any true manual simply because it shifts faster than any human can, AND never picks the wrong gear or miss a gear, that only happens to human shifters.

The Autoshift also gets 1.5 to 2 MPG better, that is about $32,000.00 per year in my small operation, money in my and my drivers pockets we would have never seen before.

I have never heard anyone complain that they have too many gears
Honestly, when was the last time you EVER split any gear in the bottom end? Unless you are specialized 120,000 lbs the is really no need too. They do have autoshift 18 speeds now. 13's, 12's, 10's.... I've been reading about going back to 9 speeds for OTR trucks. I started in '76 with 8 gears. Things sure have changed, the new trucks shift 900 to 1100 RPM and cruise at 70 mph at 1250. A hot rod truck was 250HP, now fleet trucks start at 400hp.
