to add some further thoughts...
you say that you are new to turning, so the usual advice applies- it is best to join a club and get some hands on training. It may not be easy or possible at the moment. You need to consider what you plan to turn. My emphasis is occasional hobby turning of small items and long items.
I have looked at changing my lathe a few times. Never really that seriously, and a few things have stopped me. The below is all personal to me and what I use the lathe for.
Firstly, if I want to turn spindles, getting a bigger lathe doesn't really give me that much more capacity than the jet 1014 plus extension. I haven't done stool legs, but a high stool will probably be too long or at least pushing it. For must things at the length capacity of the lathe, the diameter would be a couple of inches max. According to internet specs on both, the floor standing axi one in their hobby range is about the same between centres. For a much larger footprint of lathe I wouldn't gain anything.
Secondly, my time is limited and I dont have the time to turn large bowls. There is another consideration of the cost of large blanks, or the cost/storage space needed for lumps of tree to season. It would emotionally destroy me to spend hours on a bowl and then to turn through the bottom of it. (sometimes my dad cuts the odd tree down and I could beg some pieces before it is chopped into firewood). As much as a large capacity lathe would interest me, I would rarely use it. large capacity needs mass to it.
Thirdly, I would like variable speed, but it isnt essential. I haven't used it so I haven't missed it. changing speed takes a few seconds. For out of balance items it is probably more useful than to anything that I turn. I would consider the slightly larger jet with VS, 1220 but again I would want/need the extension, so it is probably a round trip cost of several hundred quid for me for this feature and a little more bowl capacity.
Forth, I do hit the over bed capacity of the lathe from time to time. There is no workaround for this, you just have a limit to what you can turn. To be honest, it is usually on things like a clock face where the size is not really critical (unless you have promised somebody one of a certain size). I have to admit I absolutely hate turning at the capacity of the lathe. It sounds like an angry windmill out to get me and I cannot relax and enjoy it. I have only done it on fairly thin pieces, say 30 or 40mm thick max. this is not the lathe to put on 9" diameter x 9" long blanks. If you have any desire to do that, then I can offer no advice either than to not go for the 1014. I do like big wooden platters, but I dont have any wood for that or anywhere to display one. As an aside, if you did want to do a project that your lathe can't do, book a day's training with a pro and use their lathe and guidance.
If I were starting again, I would probably look through ebay for something massive and unnecessary. When I had got over that and not actually bought anything, I think (for the turning that I do), my shortlist would be the jet 1014 plus extension, the jet 1220 vs plus extension, the Axminster 1416vs, plus extension. The Axminster is interesting as a bench top lathe because it has a better bowl capacity than most. Its advantage is that it is compact for its capacity, but I would need the extension which nulls that.
After all that drivel, I haven't changed from what I have because for what I do it is ideal. If I was starting again, with a focus on bowls (ie occasional hobby turning of bowls and few long items) I would probably look at that Axminster.
Final point (I promise), I could turn a thousand pens, and still be unable to locate a single one in our house. I think that my the third wooden bowl entering the house I would be asked "why do we need another damn bowl", and within a short space of time everybody's Christmas list would be "anything except another bowl". nobody says dont get me a pen!!!
