I bought the 35 Rem Handi barrel because I wanted to load and shoot the 35 Remington cartridge. The 25 Rem, 30 Rem, and 32 Rem all died off, but the 35 Rem lives on. There must be a reason for that. To me, the 35R has history, class, and nostalgia. I have wanted one since the Dark Ages, when I first heard of it because T/C was chambering the Contender for it. I was intrigued, I studied up on the round, and I liked what I read. Loading and shooting it is as much fun as I had hoped; the 200gr FTX makes it a bit of a thumper, while the 180 SSP is faster and more accurate. A 160 gr cast round nose bullet makes a great accurate and cheap little plinker. My 1894 and 1895 Marlins are beautiful guns, but, sorry, the 336 looks like Weatherby went cowboy or something. Until I found the Handi barrel, the 336 was the only readily available gun in 35R, but it was too ugly to buy.
I have never considered changing it to anything else, just so it's bigger and faster. I have enough bigger and faster guns. I just wanted a 35 Remington.
