I think Tokamak was largely abandoned in favor of less complex models?

Only in the world of scrappy "low-cost" commercial endeavors, AFAIK. The appeal of FRC-style reactors has more to do with lower cost of construction than any inherent physical advantages. Tokamaks are still where most of the nationally- and internationally-funded research is happening.
I was personally rooting for stellarators, but whatever operational benefits they offer over tokamaks seems to be outweighed by the incredible design complexity that they add, and they've stayed small-scale research projects relative to tokamaks.
ITER, set to be the largest fusion reactor ever built, will be a tokamak.
