I haven't heard of Giftz and ATF, but am pretty familiar with Cointed. They recently formed an alliance with Nvidia and TAS Group and this built a lot in terms of credibility. Additionally, they're focusing on Green Mining and multiple Crypto ATM launch all over Europe. For me, it is a very solid project with a professional team, long-term sustainability, and well-written writepaper. I'm pretty happy that I bought it from the very beginning. I will, however, check the rest which you've mentioned, they sparked my interest.
