I would say the Phase 3 F16 is easily the best budget EDF I have flown so far but there are plenty of other and larger EDFs now available .Cumbria have some very interesting models eg Mirage 2000 for 5 or 6s packs.These foamies weigh nothing for their size and are guarenteed to fly well.
A Ti ger Moth would be great for those flat calm days and you cant beat electric these days. I also have an EDF B747 Air Force One which is superb,possibly the only one in the UK.It is modified for 3s pack and proper flight controls.
