I have, and use, the following sets of chisels.
Veritas PM-V11, each width they offer in their bench chisel lineup. I use these the most often when I plan on striking the chisel with a mallet, but don’t hesitate to use them for paring if they are conveniently at hand when such tasks arise.
Lie-Nielsen bench chisels. Again each size they offer. I usually grab these for paring and fitting of joints. I tend to avoid using a mallet on them since I got the Veritas, but previously used them that way, and still would if the Veritas were unavailable.
Narex paring chisels, set of four. I use these when I need a longer reach. They don’t have the edge retention of the previous two premium sets, but they came without the premium price that accompanied such chisels. Narex are a good value, but require considerably more work to get them setup while the two premium sets above come pretty much requiring only a hone before putting them to use.
A set of 30 yr old Bracht chisels, bought from Leichtung Workshops during the 80s. They were my first set and they are still used regularly, more for general tasks, but they’ll still do whatever task you ask of em.
Also have a 4 pc set of Footprint chisels with the blue plastic handles. They stay in my construction bag, and get used for any task that arises when away from the shop. They sharpen well and edge retention is decent. A great set for what they are used for.
Also have a set of boxwood handled Marples mortising chisels. I only use them for chopping mortises and they function well in that capacity.
Having many chisels allows me to sharpen less frequently as I do not have a dedicated sharpening station and have to pull out my stuff and then store it again after I’ve gotten my tools back into cutting shape. I’m able to just grab another chisel, from another set if need be, and continue what I’m doing.
If I were to have only one set, it would probably be the Veritas PM-V11.
Mind you, these are all European style chisels. If you want to consider Japanese chisels, there is a whole nother world there to explore, (and you can pretty much spend whatever “high amount” you’re capable of.)
