you have to wait until you ear is completely healed to get saddle plugs in. I'm at 1/2" and have been for 6 months and still cant get saddle plugs in. I've never used tapers-just don't like the style. I love organic wood ones, they are by far the most comfortable and stay way cleaner IMO. When I was still stretching though I used stone, or steel because those are a little heavier.
I've used saddle plugs, but the only time I can use them is if I have already been that specific size for a long time because they are pretty hard to get in. I had to watch youtube tutorials on how to put them in when I got my first pair. I mainly like tapers though.
