The more tails the beast has, the more chakra it has. This is evident by Naruto having ludicrous reserves, despite only holding half (by technicality) of the nine-tails chakra.

Having ungodly amounts of chakra might help you become powerful, it's how you use it that matters. As an example, Kakashi is a hokage level shinobi, despite being able to produce only a few shadow clones, yet for the majority of the show he's stronger than Naruto, who can produce several hundred. Itachi was an s-ranked rogue-nin, and was able to easily defeat sasuke, despite having basically no chakra left.

This is one of the reasons why Jinchuriki exist. In a human vessel, their power can be controlled and used more effectively.

Of course, if you define strength as being able to shoot as many intercontinental ballistic tailed-beast laser-missiles as possible, then the more chakra you have the better.
