If the jack will fit, the wire connection will offer a level of isolation as to the continuous plugging in of products. In my years of experience the PCB mounted jack was done to save labor but the way they soldered them was ridiculous and why I always seem to have to resolder these jack due to mechanical stress breaking the joints. If you use a small piece of stranded wire, the joint will not be stressed and the item will remain soldered as no mechanical stress will be transmitted to the board. In boxes I make for the bench as in tape deck testing I use those gold jacks from off E bay as they are better not because of the gold color but the mounting and ground ring they have.
