I think you are asking our favourite strain for new growers vs just our fave strains overall?
I would say auto strains are not optimal for new growers because they don’t leave a lot of room to recover from problems. On the photo side for a new grower I would almost always say northern lights for being forgiving of sub-optimal growing situations, mold resistant, decent yields and nice smell. I would only add that the same strain name can differ between seed suppliers - if I am interested in trying something specific I try to find the original supplier. It isn’t that a secondary supplier can’t produce a good seed but it is more likely you will get weirdness from a supplier that has tried to breed up their own version of a popular seed.
Overall (as opposed to for new growers) I don’t think I have a specific recommendation. So many strains to try - I almost always try new ones each grow rather than stick with a favourite. People try to pick something based on what they personally want to achieve (e.g. strength, smell, flavour, colours, plant size, yield, mold resistance, effect, etc etc) so my recommendation would differ from person to person. I personally would probably grow pineapple chunk again if I had to pick one I’d already grown.
