Nope. They are just as accurate (.1 AFR). If you are trying to keep an eye on a tenth of an AFR while trying to drive you are asking for an accident. Use the analog output to get and record the exact readings and they will be the same whether you use analog or digital. Just looking at a gauge doesn't do much for you anyway. When you log you can know the AFR in context with the vacuum/boost, MAF, LTFT, etc. which is when it actually becomes helpful for tuning. You are not going to be able to do that when looking at the gauge while you are driving. When you drive all you want to do is know if it is off from what it normally is so that you can spot a potential problem like if it is lean at WOT then you can get your foot out of it before damaging the engine. Then analog can do that just fine and it is easier to read out of your peripheral vision.
