I own the SX730HS, and although low light performance is nothing to write home about it's a very capable camera. I bought it right when it came out last year, strictly for vlogging. The zoom is awesome, especially paired with the solid IS made for some really steady video. If you vlog, the flip up screen is a bonus. I have a review up of it on youtube (my most successful video to date lol.)
Here.The only reason it would need an upgrade would be on the sensor. Lowe light gets very grainy. But I always compare it to my 70D for video, and that's just not fair on it lol.
