Clips & Straps seemed harder to me to get more reliably in and out of. It may have been the variety of shoes I was using at the time. Before I went clipless I went for the strapless Urban Toe clips and they were a bit more reliable although I wasn’t into relatively fast cycling at the time.
The way I started with clipless was backing off the tension on the clip/foot I wanted to unclip and kept the other relatively tight (not too tight though just enough to allow you to pull away without unclipping). When you make the switch I am sure you’ll be fine
