It's down to your personal choice. In my opinion a good quality tyre and the best quality you can afford should be on your car. At the end of the day if the unexpected happens and you have a split-second to avoid catastrophy I'd prefer to have a tyre that has a good track record for grip and stability in wet/dry conditions than a poor performance tyre.
The small saving you would make would be little comfort to you lying in a hospital bed.
For example, I bought a used Peugeot 308 last year and the garage had put on brand new tyres on it for the sale. I have never heard of the brand. They were cheap and the result is they were noisy on b-roads, intrusive on the motorway and as for the grip, whilst they were okay on a dry surface, they were positively dangerous on a wet road. I had occasions of sliding/understeer on moderate bends at 38mph, whilst my other car (a heavier car) which has premium brand tryes of a narrower width can easily navigate the same bend at 50mph in the wet.
I changed the tyres after 3 weeks and never looked back.
