I did a comparison post here on PF a couple of year's back on these two lenses including some of the same subject.
In summary:
- Helios 44M 8 blades, A/M switch
- Helios 44M-4 6 blades, no A/M switch (some MC)
- Helios 44-2 8 blades, pre-set aperture
All Helii 44:
- Consistent excellent center sharpness at all apertures
- Soft in the corners at all apertures on 35mm (read that as damn sharp corner to corner on APS-C)
- Single or Multi-coated depending on model
Swirly bokeh:
- Highly variable between copies, even of the same version
- Depends a lot on subject and aperture
Special caution:
- Some (most?) Helios 44-3 will not mount cleanly to other than a Zenit SLR and require modification (grinding) to do so.
For Helios 44 pictures (with a few Helios-103 thrown in just for fun) on my Flickr account:

Note that several of those images are also in PPG

(One of my favorite lenses if you haven't figured it out yet...could results like this full resolution crop be the reason??)
