As noted by others, best way to find out is by finding a printable negative you like, start with a standard VC paper, RC and FB, print at a grade that provides the contrast you like, that becomes your standard. Then move to other brands. Not sure what are readily available in the UK, likely ILford and Foma are well represented, Adox, and Kentmere. Foma is sold under a number of house brands in the U.S. To cut cost you can start with 5X7 in 25 sheet packs. For fun you can host a blind viewing party, have friends look and give feedback on the surface, tone, and contrast, RC vs FB. And, using a cold or warm tone developers also makes a difference. The one brand that I think had a really different look is Slavich. Being a Russian company unless you some old stock may not available in the UK or US in the foreseeable future.
