Should I connect an Ethernet cable to my router or should I use TP-Link Red Home Plug?

Solution
Giagabit connection will give you 1000mbps (2000mbps looking both directions).

Powerline depends on multitude of factors. First of all there is different model levels ranging from 200mbps to 1000mbps. In reality real world speed will be 15-25%.
Powerline can also be greatly diminished in less the ideal conditions. Old wiring that does not have ground wired to recepticales and a grounding rod, or rural homes wired to all 3 phases of an electrical system, or things like higher amp electric motors and florescent light fixtures all diminish powerline speeds (or completely wipes it out).

If you have an easy to access attic or crawlspace (or unfinished basement) then running an Ethernet cable is not too hard if you have a basic...

The direct connect via cable will be more reliably fast. The Home Plug solution has the advantage that you can create multiple connections as needed, and the connections can generally be moved around. There are limits based on house wiring to that, dependent on how your house is wired.

Performance wise they should be the same. The question is more about would you be willing to pay 70€ to avoid having to run an Ethernet cable from your front entrance to your room. If you can't really hide it then you're also stuck looking at it. Of course your other option, whether you already rejected it or not, is to use 802.11ac.

(Mild aside: I find it curious that your link is for a UK product and you're quoting prices in € instead of £ and that an Ethernet cable could possibly cost 20€ to start with.)
 
If you have the option of using a ethernet cable you should always go that route even if it is a huge pain to get it installed. Unlike any other option once it is in you will never have a issue with it.

Powerline devices are dependent on how good your electical wires in your house are. You will never get even close to the rated speeds even with perfect electrical, I think the test sites show about 200m but I forget. The so called 1.2g is adding up and down together. That would be like calling a ethernet cable a 2g cable.....but on ethernet you can really get it and that is using normal cat5e cable.

If you have an easy to access attic or crawlspace (or unfinished basement) then running an Ethernet cable is not too hard if you have a basic understanding of how a house is framed/built. If you have a 2+ story home or limited/no attic/crawlspace access then it becomes significantly more difficulty
