The reason for pulling plug wires, is to see if a particular cylinder is effecting how it runs, not if it has compression loss.
It's not painful to do. You just need a plug wire puller, they are well insulated and you get no shock. Burned maybe if you touch the head or exhaust. Wear gloves
If it is a particular valve guild, it may show. You can also pull a valve cover and while running, if you have PC type valve seals, a squirt oil on the intake guilds may show a change in idle if, it's guild related.
