Talked to a few people who have been in the business for decades and consensus is that having bulbs for home use only is not a problem. Big difference if pin is out on a site. I think though that putting LED's where you can, is a good idea. I also put some in the backbox and combine with the bulbs.
LED's are harsh and bright - they all seem to be. I put them in my AFM playfield but they hurt my eyes so I combined bulbs and LED's. For me a combination makes most sense, less resistance but not too bright. Also I prefer the softer lighting look. Some pins that have 100% LED's look awful, but that is just my opinion.
