With hands like these, tactics should govern how to bid, IMO.
First, take a splinter. There are a few problems with the splinter. First, as a one-under splinter (4♦ leaving no room to bid between the splinter and a signoff), you want to be pure, whereas with a lower splinter (e.g., a 4♣ splinter supporting spades) you have room to do a little fine-tuning. The impurity is the lack of a club conntrol and the one-suited nature of the side holdings (it is all about spades on the side). So, I dislike a splinter with this hand. Not that I dislike it enough to reject it, as I may dislike other options more. But, I dislike the splinter. Thus, I would strongly disagree with any sentiment that this seems somehow to be an ideal splinter. Far from it.
Second, take a Jacoby 2NT auction. I like the fact that I have basically primes external, although the same spade problem exists. I am expecting, however, a fairly high chance of a 3♠ call (short spades), which would not leave me well-placed. If I have a better structure to show shortness, I probably end up just delaying the inevitable. Jacoby doesn't really help me describe this hand, and I am not holding a hand where partner's description will likely enable me to assert captaincy. Unbalanced and lopsided makes for bad Jacoby sequences.
Third, what about a 2/1 GF sequence? The serious downside is in the inability to focus spades quickly and the overstatement of bidding clubs with nothing resembling a stopper. Against that, however, is a fairly strong likelihood that I see a 2♦ rebid, which saves a lot of space. And, I like having the problem/lie being in the lowest ranking suit, as the space might be maximized to unwind the hand better.
My general default, however, if toward a 2/1 sequence when all options are flawed, as this maintains space and expresses possible impurity. If I start 2♣ (real clubs or just a fit in my methods) and hear and expected 2♦ (real diamonds or balanced in my methods), I can bid 2♥ (real fit in my methods) and maximize space for cues to unwind the situation. (Calls other than 2♦ seem to lead to even better sequences.) Partner might then, for instance, bid 2♠ to show a stiff (because he cannot have an honor control), and we are essentially at a similar point to the Jacoby sequence but a level lower. If parter does not bid 2♠, and hence denies a stiff (or Ace or King), then he often later will be able to cue 3♠ to show third-round control (the HUGE Queen), which seems impossible in any other auction. That analysis already convinces me that the best sequence to learn what need about spades seems to be with the 2♣ start.
All of this, of course, is because of the methods I use and the structural expectations of various alternative options. Others might not have this same analysis because the nuances of style and of available options will not tend toward my option making the most sense. But, this would be how I personally would approach this hand, FWIW.
