Whan talking about connectors... you may as well ask which ice cream is better, chocolate or vanilla because everyone you ask with have their own opinion and reasons for that opinion. I will say that there are good quality ones as well as generic clones which you may or may not get a good connection with.
One of the more popular right now in the hobby is the Dean's
Ultra Plug ( it isn't named Super, although I wouldn't be surprised to a clone named that ). These are claimed to be rated in the 40A to 60A range and have been used in many models up to the 100A range without issue since we typically don't fly at full current all of the time. Dean's also makes one called the
Micro Plug that is commonly used on smaller models ( of @ 10A rating or less ). There are a lot of generic clones of these, typically you will find them named as a "T connector" and the quality will vary a lot on these with some being good but many are unreliable from piece to piece. The Dean's Ultra Plug has one advantage that the others don't have at this time... more people use them so if you want to share batteries with others it will be easier to find someone with one that uses these connectors than with the others.
Another connector that is becoming more popular is the E-Flight E3 that is rated at 60A by Horizon Hobbies. They are usually a little bit easier to solder than the Dean's brand and are suppose to be easier to plug/unplug than the Deans though I've heard a lot of people that said the opposite ( I am not one of those ).
Another connector that I'm seeing a growing interest in, and is also a high quality plug like the previous two I just mentioned... is the Anderson Power Poles. The advantage these have is they are a crimp on connector so for people that don't know and don't want to learn how to solder, these will be a good choice. These do have a disadvantage, they require a good quality crimper if you want a reliable connection and the good crimpers are expensive. These are available in a variety of current ratings so you can get the size you want and/or need.
HobbyKing also has a connector they started making a little while back that is becoming popular despite the fact that it is cheaply built ( the plastic melts easier than the good ones ) so you don't want to exceed the rated amps. These are named XT60 and can be found around at various discount hobby shops on the internet. As their name implies... they are rated at 60A but that may be pushing it.
4mm banana plugs are also used on many discount places... I don't have specs on these but I suspect they are rated for well over 60A ( probably close to 80A ). I suspect the quality on these varies quit a bit as well.
Those are just the more popular connectors that I see talked about... I use Deans Ultra plugs myself for anything up to 100A and if I get something that needs more, I will likely use Eflight E5 's. I actually like ( technically that is ) the E3's more than I do the Deans... but more people I know use Deans and I like to be able to share batteries when needed.
