Hi Daox;
I do a lot of electronic design, I have both low end and high end power supplies.
It depends on what I'm working on. Here are a few things to look for:
1. The relatively cheap Chinese supplies work nicely, once you get a non defective
unit. Most of these are "Switching Mode" types.
These switchers are very light weight and quite portable.
However, being switchers they tend to generate RF noise and ripple on the output.
Depending on the application the ripple may not be objectionable.

2. Old used Lambda, HP, Kepco, and other high end supplies tend to me "Linear Mode"
types.
These are very low ripple and have no RF noise.
They are not nearly as portable as the transformers and regulators are quite heavy.

My personal favorite supply is a vintage Japanese Kikusui 35V 12A unit. It sits in
a permanent location on my bench. I use it every day.

3. Make sure the "Current Limit" or "Constant Current" control works quickly and
accurately.
