It’s a difficult choice but I think you need to find out what you can expect to be earning in 5 years time and make your decision on that, not the difference on what you could be earning now.
As far as ‘skilled trades’ are concerned, drain cleaning would probably earn you more than being a sparky or a cabinet maker put together. It comes down to supply and demand.
