Maybe I am missing something but I don't really see much excitement in how Arsenal play now whenever I see them and the only 2 big players I can see that they are missing are Ramsey and Koscielny. Arteta has an exciting talent in Martinelli he seems hesitant to use, young CB Saliba he hasn't given much of a chance, Torreira has been loaned out with Partey coming in, Monreal was a solid left-back but Tierney is definetly an upgrade on him. He froze Ozil out the side, Ramsey certainly is a big miss but I'm not sure it warrants a drop from 5th to firmly midtable now under Arteta.Emery’s squad was miles better. The best players from when he was there have either left or aged.
Evaluating a manager purely based on results is just being dense anyway. They were really obviously badly coached under Emery and got worse and worse the longer he was there. I don’t have a strong opinion on Arteta but I’m not having that Emery was anything other than absolutely useless.
You say evaluating a manager based just on results is being dense but what is so great about Arteta - I appreciate @sledger would have seen a lot more of Arsenal than me but I don't see the promising signs and process that others see under Arteta since this time last year. Others disagree but I seriously do not think Emery would have had this much sympathy if it was him rather than Arteta at the helm right now.
