You can't go wrong with either but always build your own kit and get some extras. I like PinballBulbs personally just because they tend to keep it simple. Cointaker has just way too much variety and most of them seem like novelty items. I've tried lots of different bulbs but in the end I always go with frosted bulbs and color match inserts, warm or cool on top depending on the color scheme. I never put colored bulbs in GI but its personal preference. I pop the dome if they are under the playfield and I want a little brighter. I do use the 4 SMD on spotlights. Oh and never try and save money and buy non ghosting, just be safe and make sure they don't ghost.
