I have purchased all my motors and electronics from Aliexpress, those motors are good enough.
As a newcomer, will be best to start with an original J head, once you gain knowledge you can get an all metal hotend. The e3d V6 will be the best, I have an hexagon and they are good but they are delicate and have some issues with PLA, I have also a V5 and unless you mod them PLA will be problematic too.
I have 2 geeetch j heads (the ones with PTFE liners) but the good ones have a protruding bolt on top and you will have to design your own connection or modify it to fit standard ones, they are pretty cheap and good, but you will need to know how to set them right for them to work properly.

You can start with an all metal hotend as long as you can Identify and segregate extruder and extrusion issues (Not everyone can) .
The new V6 have a PTFE liner in the cold zone of the hotend that help with transition from cold to hot zones, the old V5 doesn't have it unless you mod it, so in long prints or high extrusion temperatures, PLA will plug in the cold zone ruining your print. You need to use a hefty cooling system or a push-pull one, same with the Hexagon (btw the minimalistic fan that comes with it is useless) .
For someone starting in 3d printing identity if the problem comes from the hotend or the extruder isn't simple, that's why I mentioned the J head, it will be one less problem out of the equation.

The V5 works as fine as the V6. V6 is more compact, so measures and weight less. I like the way the thermistor is fixed with a screw on the V6. I dislike the small 30x30x10mm fan on the V6 for many reasons. The fan's efficiency reaches its limits at very high temperatures. It cost more than the 40mm for less efficiency, it's difficult to find silent or powerful 30mm fans at reasonable price. Maybe you'll never find a 30mm 24v fan, if you want to power your printer with this voltage. The size of the V6 makes an upgrade to a 40mm fan not that easy. BUT, if you plan to use multiple extruders, then the 40mm upgrade will fit perfectly with 2 V6 side by side.

The V6 is the evolution of the V5, so, because of the improvements it's better. I never used Hexagon or JHead nozzles. But there's something I don't like on the Jhead, it's the single heat-block nozzle. It's expensive to change it, and you can't find any size you want. On the Hexagon, I don't like the nozzle, I had a similar one delivered with my kit. I prefer the E3D style nozzle, with a flat end which allows to better squeese the fused filament on the bed/part. Otherhand, you have more grip on a larger hex nozzle. Two good point for the E3D nozzle. Maybe you can mount it on the Hexagon too. Anyway, the Hexagon have a good reputation through.Quote

For you ,what is the best hotend betwen V5 and V6?
What about the hexagon?

Ive not tried the v5 or v6 but have got the hexagon after using j-head's.
The hexagon is very good and ive had no jams or problems.
I switch between pla, abs, ninja flex and now nylon without any problems.
You have to keep a fan on the fins at all times when the hot end is hot or it could jam.
I especially like that i can switch between nozxle sizes between 0.3 and 0.5mm.
Im about to try a 0.2mm but switching nozzles isnt advisable till youve got everything working properly with one size 8deally a 0.4mm.
Especially as you need to swap them while the nozzle is at full temperature.
The latest one has a screw on plate on the heater block to keep the thermistor and heater secure. Very good idea.
I would buy another one without hesitation.
