5w 700lumens Vs 7w 720lumens

If a LED down light states the same (or very similar) lumen level, but one is 5w and the other is 7w.. is it a no brainer to go for 5w?

Or would the 7w still have better light for any other reason?

2 in question are the 4lite down light from Screwfix or the JCC x50
Is it a case that the 7w one will be cheaper because they are relying on wattage to get the lumen - whereas the 5w is using more expensive tec to get the same lumen. maybe the 7w although cheaper will run hotter and so fail sooner.
As for the difference in power usage its so miniscule not to bother --is it ?
 
I don't like them.
Nor me
I suppose that's it really but:

they are a pain to fit, spacing neatly while avoiding joists, running cables across joists,

they ruin the ceiling with large holes all over the place,

they spoil and negate some of any insulation,

The main etc in my opinion is the crap light, lighting only the floor and the deep shadows they cause.
