I had too many problems with the OE style mechanical gauge replacements. Issues with them sitting too high in the cluster and such. Had a faulty temp gauge.
Be different I'm sure if I was closer to a major center, and in the States, but up here waiting for anything from the States is months not weeks, so when they show up and don't fit or don't work it's a huge setback. Went on and on and I got tired of messing around with those, so took matters into my own hands as shown there.
