yes the offerings are very similar. the leverage of profunds is a plus but the fact that you can chart profunds sectors intraday is a HUGE bonus. you really dont have a clue where you stand with rydex during the day. see the header page of my thread (the section on sector funds) as it has links to realtime intraday quotes on the underlying indexes and chart series for the daily and weekly charts of the sectors. i also plot them on 15 and 60 min charts to fine tune decision making, but there are no links for that
