Help me pick best Options Analytics/ Strategy Website

Hey I was looking for best options strategy building or options charts website for US Stocks and indices and I came Across these

1. Option Charts
   This one I felt as Having Almost all indices but data is delayed by 15 mins
   https://optioncharts.io

2. StrikeVue
   It's having best UI among others but having very less indices
   https://strikevue.com

3. Options Alpha
   This one seems like too tough for beginner to use
   https://optionalpha.com

I am very confused on which one is the bestest.
