Sorry, dont know them, but often MFS is stated to be not the cleanest... For nics cheaper in price often generally recommended is vaperstek TH. Also heartlands is often liked and nicotine-river is a second option. RTS is often liked, but I believe they raised there prices recently. Oh, vape-clarity is another...
Sorry for not being able to offer personal opinions on these... The above, except RTS, is from 40 - 60 bucks I believe...
