Newbie needs advice

Would a big printer be slower than a small one when printing the same sized objects?
If so, can you explain why? I'm still not decided but that would be a good argument for a smaller one.

Two printers of the same make and model may not print a the same speed theoretically. Though most printers will print the same model model at close to the same speed, if the same basic settings are the same (Print Speed, filament feed rate ect...)

I have two identical 3D Printers setting side by side, If I start the Same print at exactly the same time.
One of my printers will finish the same 4 Hour Model 1 minute faster than the other.
(Why is because the Crystal clock speeds may not be exactly the same)
