My choice, for performance on a limited budget, would be the current iteration of 'Magix' 'Movie-Edit Pro', currently, from memory, a version known as 'MX'. Some years ago I purchased the 'professional' version 'VPX', which has everything which I am ever likely to need. However, to keep abreast of more recent developments, since I couldn't afford to upgrade 'VPX' on a regular basis, I adopted 'Movie Edit Pro' from v17, as a matter of course. The cost of annual upgrades, as new features are added to the 'mix' is insignificant, compared with most other software (US$100, in round figures, for example), and 'MEP', when you get down to it, lacks very few of the features which are incorporated into 'VPX'. I now use 'MEP17' (or 'MX' when that offers an advantage) as a matter of course, and I am editing, usually, at some time of most days, even if it is just compositing and rendering my 'home-grown' graphics; (currently, travelling-line animations against a (graphically-generated) green-screen background, so that I am able to superimpose walking routes of trips I have made, over wide-angle shots of same taken from a tripod; the nett effect being ever-extending lines indicating the routes, against a background where, movie-wise, it's 'business-as-usual'). All the 'marks' of 'Magix', I have mentioned here, will 'eat' this, and much more complex operations, with ease, and the learning-curve for 'newbies' is fairly moderate.
