Hiya and welcome, your best bet is to go and read some of the forum rules, use the search function on the model number and read up on the posts that relate to them. There are lots of hiddne gems in many of the posts where our community has already answered many of those questions.
No one will give you and answer of buy this one over this one as its up to you really. So many reps are really very clsoe their genuine counterparts but ALL have flaws, (this keep the industry ticking, either by design or by acutall capability) .
Lots are so very close that only the most knoweldgeable would be able to tell from a few feet away and even then would need to closely inspect it.
Clean and VSF are 2 factories that offer very good attention to detail but we cant expect gen perfection based on the prices they sell for.
Its best to look at lots of the TD's and waht they have to offer most have access to the same stocks so its really down to price and level of comfort withthe TD.
Look at the pictures (sometimes ones for sale on here are a safe bet as the pics can be less salesy, but there is the issue of warranty on a private sale.
Look at the pics and then look at the pics of a gen version on ebay or other sites and compare them.
Golds are often difficult to get right, but also thinking about the genuine articles value in the real world vs your own place in society. It looks a touch odd if working in Mcdonalds on the fries section and sporting a £25K Gold Daytona.
To be fair the model you are thinking of is quite low end value int he real world so will have far less scrutiny in real life as its far less bling and much more likely to get hold of either buy buying of a gift etc....
The less complicated the movement the better as there was other things that come into play too.
Good luck and have a good look around, find one you like and buy it, its not mega bucks if you dont like.
Also look for sale of it on here too
