@Ohsewsimple I've worked with several brands and models of overlocker .
My view is that Juki is hands down the best value for money for the build and performance of the overlocker machines on offer at all 3 price point levels.
Across other brands, many of the mid-range are okay and all brands are okay at the top end.
At the lower price points, all brands overlockers have smaller motors and tend to be built down to a price rather than up to a specification for a robust machine with precision engineering. They are intended for lightweight to medium fabrics and are not designed to be workhorses. For lots of people, what these machines can manage is all they want.
At the middle level price points overlockers from all brands are generally better built, reliably produce a good stitch and can withstand heavier use.
At the top end, the overlockers from all brands are usually well built, produce precision stitches and have bigger more powerful motors. Price across the brands can vary a lot.
My view differs about the Jaguar and other machines that open up both sides at the front. When overlocking, there are some starting and ending techniques that involve disengaging the cutting knife whilst the work is under the needle. On this type of machine, the user has to go under the work, open up the side of the machine, twist the knife out of the way and then close the door again before continuing to stitch. It's a PITA to have to do this, and in my view does not trade off against the open up for threading arrangement. Most users can very quickly master the threading of their machines. Also I find the Jaguars and similar machines can be rather noisy but so can some other models.
There are pros and cons for different overlocker models. We all start somewhere and with practice we get used to our first machine.
If its possible, then do try out some models at a shop.
