Even if finances motivated the decision, I think you made the right choice.
I have both, and tend to use the Milanese loop more... a lot more. Living in a tropical climate, there are a few factors at play:
1) The Milanese loop is cooler. You don't necessarily feel it until the Watch shifts on your arm; if you're wearing the link bracelet, you'll feel an uncomfortable heat coming from the band. The Milanese loop doesn't have this issue.
2) The Milanese loop is easily and infinitely adjustable. I don't have an underlying health condition, but I'd find that the link bracelet either felt too tight or too loose on my arm, seemingly depending on how warm and humid it was, and how much time I had spent in air conditioning. (I was also working 28-hour shifts with fair regularity at that time, which may have had something to do with it...) I never had issues with the Milanese loop loosening on its own, but realized that I was adjusting how loose or tight it was multiple times throughout the day for my own comfort. The ability to resize the link bracelet easily without tools was brilliant design on Apple's part, I agree, but you won't be making that adjustment more than once per day... and even then, hopefully you wouldn't need to adjust it that often! (I'm currently living in a place with winter, and have reverted to the link bracelet; the issues with it feeling loose or tight during the day are gone. May have just been a tropical issue for me.)
3) By appearance, the link bracelet looks more substantial. Don't psychoanalyze me for this, but there have been times when I'd temporarily be working closely with a colleague who either had a Watch with a link bracelet, or wore a traditional watch with a thick metal band, and it made the Milanese loop feel insignificant by comparison. I'd usually switch over to the link bracelet around those times. However, the space black link bracelet - despite looking wonderful up close - can give people other impressions. One person remarked to me that they thought the space black link bracelet was plastic, instead of metal. In certain lighting and from certain angles it does have a plastic-like appearance. In other words, just because it's Apple's most expensive band doesn't mean everyone will realize that they're looking at anodized stainless steel with a diamond-like coating - some people will evidently think it's a cheap plastic bracelet! This is unlikely to be the case with the standard "silver" stainless steel link bracelet. I'd still consider using the space black link bracelet as a more formal band, but be aware that some might not appreciate it... and I still think the space black Milanese loop looks pretty classy.
Either option is a definite step up from the bands that come with the watch.
Ah, and one thing the Milanese loop has over the link bracelet? The way it sparkles in a subtle way. Even though I've had it for years now, I still get enjoyment from admiring the Milanese loop in subtle lighting, slowly rotating my wrist to have the band catch the lighting at different angles.
(For what it's worth, my space black Milanese loop was the only one I bought from Apple; my space black link bracelet, stainless steel link bracelet, and stainless steel Milanese loop were all bought second-hand through eBay. It's a risk, but careful inspection reveals them all to be genuine or, at worst, grey market... and I saved quite a bit that way. It can take a long time to get what you're looking for and at a decent price, but if you're patient you'll probably get it. Good luck!)
