Toilet vs potty chair

We have been doing lazy EC since my daughter was 6mos old. She seemed to get distracted if I put her on a potty chair, so we have used a seat reducer on the toilet instead. I'm hoping to potty train her in the month or so (around age 2.) Should I try to use potty chair, since then I can have it close by to pop her onto if I see her starting to pee or poop? As opposed to grabbing her and running to the toilet in the bathroom. I'm just wondering whether it would be more confusing for her to add in using the potty chair, and if sticking to just using the toilet would be more familiar. Does anyone have experience with this or recommendations?
