My first babysteps in offcamera flash was with an old Nikon SB26 and a set of dump triggers. Having the ability to place the flash and let it bounce light of a wall was eye opening to me, man the possibilities and the quality of light I suddenly had access to. But having to change the setttings on the flash itself was annoying and change ISO and apperture on camera wasn't optimal so I looked at the brand new Nissin Air and Di700 kit.
Then I noticed Godox announced the TT685 and saw their Speedlight on steroids, the AD360 and that was it, the bulk and weight of a big speedlight (roughly, ok + some

) and the power and omnidirectional bulb of a studiostrobe + the ability to work on the same radio system as the smaller speedlights was awesome. So with that in mind I ordered a TT685 and a X1T. The trigger was on backorder so they send me another TT685 to use as trigger untill the X1 arrived. It wasnt more than 10 minutes untill I realized how big it was on my Sony A6000 and it would do a lot better off camera like the other one so I ordered the trigger elsewhere. I didnt plan on having 2 speedlights but man I loved it.
Fast forward a few years the planned purchase of the AD360 has been followed by the AD200, my camera is now a Fuji X-T2 but I havn't bothered getting a hotshoe flash specifically for that yet, only a trigger and an update of the TT685S' and the Godox system runs perfectly with either the cameras. Only letdown is the lack of HSS with the Fuji/AD360 combo
Today the Godox system has evolved with lowcost mainspowered studio strobes, battery powered studio strobes and the new AD200 which is smaller than the AD360, only slightly bigger than the TT685 but with 3X the power, cheaper than the highend Canon or Nikon models and much more versatile for off camera use
(it has no hotshoe so its OCF only) all controlled from the same triggers making it even more versatile.
I wouldnt consider a brand that only offers speedlights. Good as they may be the flexibility of a full system is where its at even if youre not considering the bigger lights right now
