Do you prefer dolly or slider?

[DDirector]

I'm still in a long debate deciding which would better suit me.

Dolly (Matthews doorway dolly):

Pros
-Track is on the ground and can easily do in/out shots
-Camera operator/1st AC can sit/stand on the dolly
-Can be as long as needed in both straight and curved
-Can be set up in places the Slider cant
-Can mount a jib on the dolly
-Can be used on a track and on the ground

Cons
-Working solo can be more difficult to setup/loan/unload
-Heavy (Often need 2+ people to help)
-Size (It is big, but still manageable for transport)



Slider (Losmandy Explorer Trolley):

Pros
-Lightweight
-Can be moved and setup by yourself
-Can be set up in places the dolly cant

Cons
-Straight track only
-Cannot do in/out shots or the track will be in the shot
-Cant mount a jib on the slider
-Camera operator/1st AC must follow with camera




I have never worked with a slider before. I have only worked with dollies; Matthews doorway dolly, Peewee dolly, Chameleon Dolly.
This is for work on short films, feature films, commercials, and music videos
