I don't actually own a Cyclone so can't really comment on any pros or cons but I do have a Jagstang
The common complaint with the Jagstang is the trem system and the narrow neck, the nut width is 1.5625, the switches being a bit high so they can catch your hand (this is easily fixed though)
The cyclone uses a Strat style trem system which is much more stable then the Jagstang, personally my Jagstangs trem is fine, I've serviced it and it works great but not everyone is a guitar tech like me
The cyclone has a wider neck 1.6785 nut width, which is in between a Gibson and Strat nut width.
If you've got smaller hands then the thinner neck on the Jagstang maybe a better choice.
Essentially they're very similar guitars, with much of the same functions, the Jagstang is a bit smaller then the Cyclone, has a different pickups switching system with has on and off phase switching. They both are HS and the cyclone hasn't got a slanted humbucker.
The Jagstang has a vintage feel to it due to the radius, it's the same as my 57 Strat.
I got a Jagstang as I'd wanted one in my collection since the late 90s, now it's here and I play her lots. With maintenance the issues of trem stability can be fixed, just don't expect dive bombs
If you're not playing lead and a trem isn't something you use then it's also easy to (block off) as is the Cyclone.
Hope that helps a bit, anymore questions ask away and i'll try to answer
