No offense, but it seems like people are picking the "personal favorite". I thought op is asking the BEST camera company in current market.
How do you define 'best'?
Best build quality and durability? Best image quality? Best track record of not abandoning buyers of previous models? Best for landscape, best for low-light or best for portraiture? Best value for money? For that matter, what's 'value for money'?
Children love to ask what's 'best', but as they get older, they generally realize that there's rarely a single answer. If there were, that single 'best' would displace everything else. But there's always someone who wants something cheaper, or lighter, or stronger, or better-finished, and is willing to put up with deficiencies in another area in return for more of the quality they want.
Then there's the question of whether you can afford the best. I don't know if Lobb boots are the best but I do know that I can't afford £3394, plus VAT, for a pair, made to measure though they are. Likewise I think I'd rather have a Bristol than a Rolls Royce, but as I can't afford either, I am in no position to judge.
By the same token, although I've owned or used a lot of cameras, I've a great deal more experience of some brands than others: I've used hardly any Canons, for example, no more than half a dozen models, rangefinder and SLR together. This is a self-reinforcing situation: I'm likelier to use cameras I like or am familiar with,
and have lenses for, in preference to cameras where I've had bad experiences or no experence. I certainly can't judge current Nikon pro DSLRs against current Canon pro DSLRs, and some of the cameras I'd rather have than either are not, shall we say, exactly mass-market: Alpa, Gandolfi, Linhof.
So yes, there's not a lot more anyone can do than to list their personal favourites, based on their own experience, which may span decades and cover numerous brands or may be a few years principally with one brand. The whole poll has to be fairly light-hearted and subjective: there is no alternative (TINA strikes again).
Cheers,
