GLA-SOU is a great route and allows me to visit family on the south coast far more easily than any of the alternatives. I've not yet tried Loganair south from Scotland but in general their fares seem prohibitively expensive compared to EasyJet.
There’s also Bournemouth - Edinburgh on Ryanair which can be very cheap although the public transport offering at Bournemouth Airport is non-existent compared to Southampton.
