Right tilt or left tilt? The arguments are a bit like the Big Endians and the Little Endians in Gullivers Travels. So, as they say in Monty Python, "Is this the 5 minute argument, or the full half-hour?"
I'll take the argument from the point of view of a right hander who works conventionally, i.e. I stand to the left of the saw blade. For me a right tilter is the way to go. I feel they are safer. Left tilters put the blade over towards you, towards the mitre guide and nearer to your hands. I feel this is especially dangerous if you work withut a guard over the blade, as I know many people do in the USA. A right tilter puts the blade away from you, away from your hands, but can lead to trapping of material against the bench if you use an unmodified straight through rip fence (the norm on US saws until recently) and of course that potentially leads to a kickback. As a European I'm familiar with and "acclimatised" to using a table saw with either a short rip fence or a through rip fence with a ripping plate attached (effectively making it into a short rip fence). To me that feels safer - heck it is
safer than the long fence approach and sidesteps many of the issues you have with kickbacks (although not fully because there is also the need for a riving knife, or failing that a splitter).
Over here in the UK we only really had one brand of table saw which came with a left tilt blade, the Startrite. Everything else I can ever recall was a right tilter. The Startrites also came with a through fence, although (from memory) their manuals recommended attaching a ripping plate (short sub-fence) to the main rip fence when rip sawing or using the rip fence as a length stop for repetitive cross cutting
Incidentally, every current European saw I know of tilte right and comes with a short rip fence (generally a sliding one)
