No idea about the others, but for YAC it was never GPU resistance although a lot of idiots used to belive this.
YAC is currently mined mostly by GPUs, but I think this will change.

I'd say YAC is nearly 99.9% ASIC resistant unless it would grow to a size far far bigger than bitcoin today. It changes memory requirement over time so a new ASIC would have to be made for every new n-factor since it doubles memory needed. Currently this happens 2 times per year but there will be less and less n-changes in the future. There would also be competition from botnets/servers/... so ASICs are unlikely to break even on development costs.

An n-change also favours CPU strongly over GPU so it will make it harder and harder for GPUs.
YAC is the only crypto I'm aware of that adapts to technological innovation by making hashing "harder" over time.
There had been FPGA implementations, but they do not function anymore. For most cryptos it will be there hadn't been
FPGA implementations, but in the future this will be possible. YAC's the other(better) way round.
