Thermal mass in an oven is a good thing. It helps maintain set point as various thermal loads enter the chamber.
Thermal mass is augmented by the use of convection. This means a small mechanical structure can be made to approximate larger thermal structure with the view to improving process window.
The question how ever is : Is a Convection Oven a Better Choice for a DIY SMD Reflow Oven?
The answer is YES. But better still, a vapour phase oven is significantly better than reflow ovens relying on air and IR for transfer oh heat.
