Giving Up On Gooseberries

I bought one each of Hinnonmaki Red and Hinnonmaki Green from Aldi maybe 3 or 4 years ago. They actually both turned out to be Red but whatever. The sawfly found them in the first year and every year since. I have them in pots due to lack of space in the ground. I think this year is the earliest I've seen sawfly on them. I knew they were there and had picked off a few leaves with tiny caterpillars on, with the intention of spraying the plant with neem and soap before they got out of hand. Then a few days later they've gone from looking really healthy and covered with foliage, to skeletal and almost leafless in the photo. There's also scale insects on some branches. 

I don't really like gooseberries that much and they're difficult to handle due to the spikes, but the flowers are good early forage for bees. 

Can anyone convince me to keep these gooseberry plants before I chuck them in the green bin?
