Felt Tip Pens - ASDA vs Staedtler

Many a time, I have been stuck as to wether to buy low price, supermarket's own brand felt tips, or to go for a higher quality pack that will last longer but will cost much more. Here I have grouped the advantages and disadvantages of each option.

ASDA - £0.22 10 Pack Fibre Tip Pens

Here is a picture of the ASDA smartprice Fibre Tip Pens. You can get these from Tesco and other major supermarkets (obviously their own brand). Cheap, middling quality.
Advantages -
The price.
The colours are fairly bright.

Disadvantages -
They don't last long.
There isn't a huge range of colours.
They squeek LOUDLY.

Yes, they'll see you through. However, if you have a higher budget and prefer high end quality to low end, then you might want to use:

These Staedtler Triplus Colour Pens are amazing! Not only will they last longer thsn the ASDA fibre tip pens, they also create more vibrant colours. Are there any disadvantages? Maybe just 1.

Advantages -
They are brilliant quality.
They are really bright.
They are comfortable to hold.
They don't squeek.
They give bold, clear lines.

Disadvantages -
They cost £5.80. That's 58p per pen.

So overall, which do I prefer? Low end, cheap, squeeky, supermarket own fibre tip pens? Or high quality, Staedtler, not very cheap triplus colour pens? Staedtler.
