I have the Hyperion Eos 720i super duo3, it's been a great charger,(still is) but if I needed a new charger I think I'd go with Hitec 4, they are on sale most places for $129.99 Fella I fly with has one, and it does everything my hyperion does, for less than half the price.
Keep in mind the Hyperion 720i is a 1000 watt charger, whereas the Hitec X4 is only 50 watts per channel. If all you're charging is smaller 2-3s packs then you won't have problems but getting up to 4s+ is going to take a while to charge depending on capacity.
