You show your location as the UK, there are no such thing as ultralights in the UK.
The Aeroprakt A22 is sold in the UK as the "Foxbat" which is a microlight. Significant microlight hours don't count, in the eyes of UK CAA, towards an ATPL. LASORS will tell you what tiny fraction of those hours you can count.
The B&F FK9 is not approved in the UK;if it was it would be in the light aeroplane / VLA category so the hours would count. If you can get to fly a D registered example, then the hours *should* count, but I'd check with UK CAA before spending money.
There are however lots of very inexpensive LAA homebuilts or vintage aeroplanes which you could buy a share in, and where the hours will count. To name a few: VP1, KR-2, Avid, Kitfox, Rans S7, Jodel D9....
Worth making an opening investment by joining the LAA for a year, if you're not already a member.
Patowalker Regarding the FAA ATP, presumably UK microlight hours above 115kg ZFW (which is all but the SSDRs) count in FAAland, because not being ultralights under FAR-103 they're just aeroplanes there. This actually opens up the interesting idea of US pilots coming to the UK for cheap hourbuilding
