Deans all the way my friend. I have personally witnessed Deans being used in planes with 100+ amp current draws.

I've been pretty impressed with the XT60 connectors from HobbyCity. Been running them in 1/8th scale buggy and truggy for a few months now. The EC3/EC5 connectors are good although they are are not easy to reuse.

XT60s are simply re-packed bullets, and they are small bullets 3mm or 3.5mm, NOT comparable to Deans in terms of current handling. EC3, same if not worse for it has thin lantern shaped conductor and small contact points.

Deans all the way, and yes, knock off Deans all the way. They are the only thing i saw that performs far beyond the genuine.

I started using EC3 on my RX lipos and regulators. I found that even with my best soldering job, Ultra Plugs had a tendency to drop connection to the V Regulator when twisted or sometimes just touched. Don't want dropped connections on a 35% planes, now do we.

The EC3's are easy to get in USA and so I use them for my big RX packs.

Still use Ultra Plugs on 90% of my packs, but may be phazing out that as well.

EC3's by the way will handle 70A draws. (3.5mm bullets) Not sure what Himalaya means by bad connections (yes, its probable after 100 disconnects or so, but so are the Deans, the springs break off)

the 3mm XT60 I would not use for anything over 2100mAh. The XT60s should be great as well for RX packs.

Actually they are all about equal in performance. It really depends on the application and the user preferences. If a user already had invested in Deans connectors then they are likely to stick with them. But a user who hasn't gone one way or the other is likely to go with whatever came installed on the battery packs.
I haven't done anything with EC3 connectors on anything, but I do use Deans or XT60 connectors. One day I sat down a made a bunch of adapters for the XT60's so I can plug the battery packs in to most anything now.

As far as the performance of these connectors, in my opinion, it has a lot more to do with the quality of the solder connection.

I found that the Deans can be more difficult to get a proper solder job on than the EC3/EC5, the EC3/EC5 being a solder cup allows for 360 degrees of contact with the wire, thus making it easier to get a good solder connection.

Also, being able to solder one wire and inserting it into the connector before working on the other wire, is a little safer than working with the Deans.

I also, took a small piece of wood and drilled holes into it that hold the EC3 and EC5 pins, thus I do not have any heat loss and the pins are held steady.

EC3's are rated to 60A continious, are very easy to solder and don't require shrink wrap. Deans have no true rating, are a PITA to solder and look ugly.

I've had the springs on 3 deans fail. switched to EC3 and never had another problem.

I only had springs on the fake chins Deans clones fail never on a real deans plug.

Deans are a pita to solder and use. After years of using them I bought some XT60s to try and have never looked back.

I hate to say it you guy's must not know how to solder or must be using the wrong soldering iron because i never had any problems at all soldering wires to deans plugs?

Great, a new version of the Deans vs APP debate. I think it first surfaced when RCG was the Eflight mailing list back in the last century

LOL..

with regards to current handling capacity?
well my 50cc EG Aircraft MX2 on 10s with a rimfire 50cc motor at 230kv with a xoar 23x8 prop is over 110 amps WOT. XT60's seem to be holding up just fine thank you.
